I have a form that has several sections that are not visible unless a certain radio button is checked. When I submit the form, the validation scripts for the elements within the hidden section are still triggered. How can I prevent these validation scripts from operating if the section is hidden?

Check to see if you have one or more sections or fieldsets nested inside each other. If so, then the validations won't turn off due to performance reasons. Please rearrange the sections (or fieldsets), so the section holding the fields won't be nested in a parent section. Then it should work.

Another possibility would be to create rules for every field rather than by section, but this could require a lot more visibility rules.
