How to detected duplicate item using Power Apps
Hello,
I have problem how to detect duplicate item before saving it in sharepoint list using Power Apps. I wrote this function based on what I found in Internet but there are errors and I can't uderstand what is wrong.
My function:
If(IsBlank(LookUp('BrowseGallery2_1', title=DataCardValue5.Text)),
SubmitForm(Form1),
Notify('Error duplicate values detected", NotificationType.Error)
)
Shown error: The function 'LookUp' has some invalid arguments.
Incompatible types for comparison. These types cant't be compared : Error, Text.
I don't uderstand the errors. The type of column title is text.
I will be grateful for every answer. Thanks 🙂
Domi333 you're getting the error because you're trying to lookup data from the gallery whereas you need to lookup from the data source (SharePoint list etc).
