@JayMagness Thanks,
I tried writing this in the Reset property of the DataCardValue but it doesn't change anything : If(Radio7.Selected.Value = "Non", true, false)
So basically I have this first field :

If yes is selected, these next fields have to be editable (which I did by writing If(Radio7.Selected.Value = "Non", DisplayMode.Disabled, DisplayMode.Edit) )

Now, imagine I check yes in the first field, enter text in the second fields and then submit the form (the form is saved in a SharePoint list). After that, I go back to my form to change my answer and decide to check no in the first field. What I would like is for the second fields to become disabled and to reset themselves so that when I submit the form once again, the second fields appear empty in my sharepoint list.
Do you know haw to do that ?
Thanks,
Max
