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!
