Check if One Radio Button in Each Group is Checked

Hi there!

I created a button to validate if I have 1 radiobutton selected in each of the 4 radiobutton groups. (None of this checkboxes can be selected in the onshow of this page
(the selection can only be done by the user action).

I know how to validate if one of the radiobuttons is selected, but i never done it in multiple groups in one validation. Can you help me?

Thank you :slight_smile:
