Hi everyone,
I'm new to Powerapps, and I'm learning how to hide this text field datacard (nombre_place_Datacard1)

according to this boolean datacard value (disponible_Datacard1)

I wanted to make the first one (nombre_place) invisible once the second one (disponible) is set to "false", with this formula placed in nombre_place_DataCard Visibility option :

With DataCardValue4 being from disponible_Datacard1
But so far, it's not working...
Any idea where could the problem come from ?
Thanks in advance !
