Problems with my Repeating Group and sorting two different datatypes with multiple different fields!

This makes so much more sense! Do you have any recommendations on how to match users in my type of app? Possibly without option sets? Because this is my demo… but in my big project app users can pick what they want, answer questions about it, and then get matched. And the questions will be different for what the user clicks vs this app demo where the user must answer every single question (Option). I am assuming that instead, I could just create more data fields and datatypes! But again thank you so much.

What do they pick and what kind of questions are answer?

Figured it out! Never mind. Thank you so much for the help.
