Data entry form help!
Hi
I have a spreadsheet with 2 sheets.....Sheet A (data) and Sheet B (input). I have created a table in A and managed to create a data entry form. In sheet B I created a button and attached a macro which opens A and the data entry form.
The first problem I have is that whenever I try to enter data I get "Cannot extend table or database".
Now this is my wishlist...please note that I am not fluent in VBA etc.
1. Can I create a data entry form that is always displayed in B to enable creation of new data and searching?
2. How do I get rid of the error I am currently getting?
I was hoping to attach a sample but can't see where to do that.
Many thanks
Debbie
It seems like you are trying to create a data entry form in Excel 365 that allows you to input data into a table and perform searches. To address your questions:
- Create a Data Entry Form in Sheet B: To create a data entry form in Sheet B, you can use Excel UserForms, which allow you to design custom data input forms. Here is a simplified guide to creating a basic data entry form:
Step 1: Create a UserForm
- Press Alt + F11 to open the Visual Basic for Applications (VBA) editor.
- In the VBA editor, go to "Insert" > "UserForm" to create a new UserForm.
- Add controls (e.g., text boxes, labels, buttons) to the UserForm to design your data entry form.
Step 2: Code the UserForm
Next, you will need to write VBA code to handle interactions with the UserForm. For example, you will write code to add data to your table when the user clicks a "Submit" button.
Here is a simple example of VBA code to add data to a table:
vba code:
Private Sub SubmitButton_Click() Dim ws As Worksheet Dim tbl As ListObject Dim newRow As ListRow ' Set the worksheet and table Set ws = ThisWorkbook.Sheets("SheetA") Set tbl = ws.ListObjects("TableName") ' Replace "TableName" with your table name ' Add a new row to the table Set newRow = tbl.ListRows.Add(AlwaysInsert:=True) ' Fill in data from UserForm controls newRow.Range(1, 1).Value = TextBox1.Value ' Replace with your control names and values ' Close the UserForm Unload Me End SubStep 3: Show the UserForm
You can add a button to Sheet B and attach code to display the UserForm when clicked. Here's a simplified example:
vba code:
Private Sub ShowFormButton_Click() UserForm1.Show ' Replace "UserForm1" with your UserForm's name End Sub- Resolve the "Cannot Extend Table or Database" Error:
The "Cannot extend table or database" error typically occurs when you are trying to add data to a table, and Excel is unable to determine the table's size correctly. You can try the following steps to resolve this issue:
- Ensure that your table has headers.
- Check if there are any merged cells, blank rows, or columns within your table. These can interfere with the table's structure.
- Verify that there are no empty rows below the table in Sheet A.
- If you are using a table formula for column calculations, ensure that it is correctly configured.
- If the issue persists, try recreating the table in Sheet A to ensure its properly defined.
By creating a UserForm for data entry in Sheet B and handling data submission through VBA code, you can achieve your goal of entering and managing data more effectively. The text, steps and codes were created with the help of AI.

Thanks so much....I am amazed that I have got this far so far....still a way to go.
I have created the user form:
I tried applying the code to 'submit' and 'new entry' as you can see i have a problem with the latter.
I appreciate your patience (this is all new to me) but what have i done wrong to get the error and how do i test the user form.
I am not sure how to open the excel spreadsheet with the user form displayed.
Code for the 'search' would be great
VBA Data Entry Form and Search Functionality in Excel
1. Resolving the "Cannot extend table or database" Error: This error typically occurs when Excel cannot expand the table due to existing data, merged cells, or blank rows/columns surrounding the table. Here’s how to address this issue:
- Check Surrounding Cells: Ensure that there are no merged cells or data in adjacent rows/columns around the table. Excel needs space to expand the table.
- Table Boundaries: Ensure the table doesn’t have any blank rows or columns within it. Blank rows or columns can interrupt the table’s structure.
- Formulas: If your table columns have formulas, ensure they are correctly set up and not causing issues with the table’s auto-expansion.
If the problem persists, consider recreating the table to ensure it's correctly defined.
2. Making the UserForm Always Visible on Sheet B: To have a UserForm always available on Sheet B for data entry and searching, follow these steps:
- Create a UserForm:
- Open the VBA editor with Alt + F11.
- Go to Insert > UserForm to create a new form. Add the necessary controls like TextBoxes, Labels, and Buttons.
- Add Code to Show the UserForm:
- In Sheet B, add a button and assign it a macro that shows the UserForm:
Vba Code is untested backup your file first
Private Sub ShowFormButton_Click() UserForm1.Show ' Replace "UserForm1" with your UserForm's name End SubSubmit Data from the UserForm:
- Add a button (e.g., "Submit") on the UserForm and attach the following code to submit data to your table:
Vba Code is untested backup your file first.
Private Sub SubmitButton_Click() Dim ws As Worksheet Dim tbl As ListObject Dim newRow As ListRow ' Set the worksheet and table Set ws = ThisWorkbook.Sheets("SheetA") Set tbl = ws.ListObjects("YourTableName") ' Replace with your table name ' Add a new row to the table Set newRow = tbl.ListRows.Add(AlwaysInsert:=True) ' Fill in data from UserForm controls newRow.Range(1, 1).Value = TextBox1.Value ' Adjust control names accordingly ' Close the UserForm Unload Me End Sub3. Adding a Search Functionality: You can also add a search function to the UserForm that allows users to search for existing data. Here’s a simple way to implement it:
- Add a Search Button and TextBox:
- Add a TextBox (e.g., "SearchBox") and a Button (e.g., "SearchButton") on your UserForm.
- Search Code:
Vba Code is untested backup your file first
Private Sub SearchButton_Click() Dim ws As Worksheet Dim tbl As ListObject Dim foundCell As Range Dim searchValue As String ' Set the worksheet and table Set ws = ThisWorkbook.Sheets("SheetA") Set tbl = ws.ListObjects("YourTableName") ' Replace with your table name ' Get the search value from the TextBox searchValue = SearchBox.Value ' Search in the first column of the table Set foundCell = tbl.ListColumns(1).DataBodyRange.Find(What:=searchValue, LookIn:=xlValues) ' Display search results If Not foundCell Is Nothing Then MsgBox "Found: " & foundCell.Value, vbInformation Else MsgBox "No match found.", vbExclamation End If End SubThis simple search will look for a value in the first column of the table and notify the user if a match is found.
can you look through this code i am having issues with the form section

Troubleshooting the Special Education Database Setup in Access VBA
- Error Handling and Debugging Tips: To troubleshoot and ensure your Access VBA code runs smoothly, you should implement robust error handling and ensure each part of your code works as expected.
- Issue with the Form Creation Section: The code to create the Student Entry Form appears to be generally correct. However, if you're facing issues, here are some tips:
- Check for Existing Forms: Ensure that the form doesn't already exist, as your code checks for this and might exit early if it does:
Vba Code is untested backup your file.
If DCount("*", "MSysObjects", "Type=(-32768) AND Name='" & strFormName & "'") > 0 Then MsgBox "The Student Entry form already exists.", vbInformation Exit Sub End IfIf you want to overwrite the form or create it anew, you might need to delete the existing form first.
- Form Control Creation: The function AddControlToForm is called but not defined in the provided code. Make sure this function is defined properly elsewhere in your code. Here’s a simplified example of what this function might look like:
Vba Code is untested backup your file first.
Private Sub AddControlToForm(ByVal formName As String, controlType As AcControlType, controlName As String, controlCaption As String, leftPos As Integer, topPos As Integer, Optional width As Integer = 0, Optional height As Integer = 0, Optional controlSource As String = "") Dim ctrl As Control Set ctrl = Forms(formName).Controls.Add(controlType, controlName) With ctrl .Caption = controlCaption .Left = leftPos .Top = topPos If width > 0 Then .Width = width If height > 0 Then .Height = height If controlSource <> "" Then .ControlSource = controlSource End With End Sub- Review Error Handling: Your code has a general error handler at the end of the CreateStudentEntryForm subroutine. Make sure to identify the specific line causing the error by stepping through the code with F8 in the VBA editor. This allows you to see where exactly the error occurs.
3. General Advice:
If the form creation part is causing issues, test the code in smaller chunks. Create a simple form first, adding one control at a time, and see where it fails. This will help you isolate the problem.
I hope these explanations help you with your VBA projects.
