CTLPOTTER 

To create a dropdown menu for suppliers in Excel using Data Validation while ignoring duplicates and blanks, you can utilize a dynamic range combined with a formula to extract unique values from column E. Here is how you can do it:

1. Create a Named Range for Unique Suppliers:
• Select the cell where you want your dropdown menu to appear.
• Go to the Formulas tab > Name Manager (or press Ctrl + F3).
• Click on "New" and enter a name for your range (e.g., "UniqueSuppliers").
• In the "Refers to" field, enter the following formula:

=UNIQUE(FILTER(E:E, E:E<>""))

• Click OK to save the Named Range.
1. Apply Data Validation:
• Select the cell where you want the dropdown menu.
• Go to the Data tab > Data Validation.
• In the Settings tab, choose "List" from the Allow dropdown.
• In the Source field, enter:

=UniqueSuppliers

• Click OK to apply Data Validation.

This setup will create a dropdown menu for suppliers in the selected cell, containing unique values from column E while ignoring duplicates and blanks.
