Relationships with incomplete information

I have a table with questions for users. I want to expose data based on those questions. For example, if someone answers YES to a question, I want that persons contact info shown.

I have watched the videos on single and multiple relations, but I don’t know how to complete this programming. May I ask for some help?

Thanks

So you want an interface with a choice component for an answer, and a contact component that will only show when the answer is yes?
