I have side by side template used. In each question, I have 2 sub questions. Now each sub question has 3 column question to be answered. 1st column is check box, 2nd one is radio , 3rd is radio, and 4th has optional comments which is mandatory only if 2nd & 3rd has 'low' value selected.

I want to ensure on click on next button this validation to be performed so that it becomes mandatory for user to answer all questions. Request to please or share snippet to get it done.

Thanks.
