I have two Section controls, A and B. Section A holds 12 checkboxes. I want to keep Section B hidden until at least one checkbox in A is used/checked. Any of the 12 used should cause Section B to appear. I have used conditional formatting in Section B with 12 conditions (1 for each checkbox) spread over 3 rules, but this does not seem to work. Is there a smart way with conditional formatting/rules to unhide Section B if Section A has any activity?
