I have a field rule that shows a message when the "no" radio button is selected in Section B. There are a number of selections in Section A, and each one opens up a different Section B, however, the field rule applies to all the different choices that occur in Section B. 

The problem is this - when "no" is answered in Section B, the field rule kicks in and asks the user to select a different option in Section A. However, when the user selects a new option in Section A, the field rule is still showing.

How do I tell the field rule to go away once a new selection is made in Section A (but keep the field rule for if "no" is selected again in the new Section B)?
