Hi Everyone

I need to make sure that if someone selects "Yes" in a dropdown Field, they are required to attach a file.

I tried the following formula:

If(Sprache_DataCard2.Selected.Value ='Ja'.'Nein',DisplayMode.Edit,DisplayMode.Disabled)

Unfortunately I get several errors such as: "Selected" cannot be identified, "Valued" is not a valid name etc.

Can you help? Thanks!

Hi @Michaela3 ,

The issue is that you are referring Sprache_DataCard2 instead of its' value (DataCardValueXX_X), so please try this:

If( DataCardValueXX_X.Selected.Value ='Ja'.'Nein', DisplayMode.Edit, DisplayMode.Disabled )

You will have to replace XX_X with the right numbers for the actual DataCardValue control in Sprache_DataCard2.
