I have a repeating group within a repeating group, each with a different type of content. I’m trying to make changes to a List of Things and place a constraint on the change.
I had a look at your Data structure. Under User, I didn’t see any List of Things. In order to link the data to each user, I think you need to have a List of Things as a field in the User Thing.
Also, under Gig, you have a List of Users. I don’t think that’s right.
And finally, as for creating the secondary link, to start with, it might be simpler to place the secondary Repeating Group outside of the primary Repeating Group.
Hopefully, if I’m wrong, someone will correct me. I’m new here as well.
