I am building a form that has different sections showing based on radio button selection at the top.  I want to have some required fields, but if I set them required in the designer, they are always required (even when hidden).  I need a way to set fields as required if radio button value = "something".

I found dynamically change required fields, and that helps me get started, but how do I set column 1 & 2 (required but not 3) on a table?  Also on an address field, I want to require address1, city, state, and zip, but not address2 or country (I would even like to hide country).
