Issue with Repeated Group and Dynamic Multiple-Choice Options

I have the following problem: I have a repeated group with a text question, and I need to create a second repeated group with a multiple-choice question where the answer options are the text responses from the first group, and it includes the option “None.” The problem is that the number of times the text question can be repeated is n, not a fixed number. How could I solve this? Thank you!

Hello,
I guess the second repeat question is outside the first repeat. Can you try this and tell us your experience.
First repeat.

2nd repeat group

begin_repeat| rpeatgroup2| Peoples Cross interest
select_one ${Q1}| Q3| Q3. Who is you best friend?

end_group
