Hi all,

How I can verify when a button is pressed if the Collection (specific column) already contains a value?

Basically I have a textbox that allow users to add email address, and I want to make sure that the users do not add repeated values.

I want to notify(information) users if the value already exist on the table

My code:

If(Filter('collection',[@email].Text=true),Notify("Already Exists",NotificationType.Information))

Hi @Rubenfrreis

Something along the lines of this should work for you.

If(CountRows(Filter('collection',[@email] = txtEmailTextbox.Text))>0, Notify("Already Exists",NotificationType.Information) )
