Hide or show field based on another selected field value in Powerapps

Question

I have a number field in powerapps (app from a SharePoint list) that I only want to show if the selected value in in Soort-Datacard2 is "Brandstof".

I use this formula for Visible in Powerapps:

If(Soort_DataCard2.Selected.Value="Brandstof";true;false)

This formula results in an invalid argument type. What am I doing wrong?

Answer 1

You are referring to the card named Soort_DataCard2, that probably has another control inside it you want to refer to.

It is probably named DataCardValueX with a unique number at the end:

Here, "Branch" is a Choice column.

Once you have found the right control, enter this in the Visible property of the card you want to show or hide:

You do not need the IF statement, as this returns a boolean (true/false) value by itself.
