Radio button choices make various fields required?

On this forum, I've searched but I can't locate the exact solution to my problem.

I'm creating my form in AcrobatDC. Using three Radio buttons: "Radio1", "Radio2", "Radio3", I want to make various text fields Required, depending on which Radio is selected. Some text fields will be required for all Radio selections, some will be required for only a single Radio selection. How do I make each radio button trigger different sets of required fields independent of each other?

Example:

1. "Radio1" selected; makes text fields "Text1", "Text2" "Text3", and "Text4" required.

2. "Radio2" selected; makes text fields "Text1", "Text2", "Text 5"  and "Tex6" required.

3. "Radio3" selected; makes text fields "Text1", "Text6", "Text7" and "Text8" required.

I've figured out how to make a Radio button trigger a single required field with basic Javascript, but with this many variables, I'm out of my league.

Your genius is greatly appreciated!
