James I do appreciate your assistance through this, however I do still have some unanswered questions that may determine if I am able to use Survey123 at this time:
Is there any known method to reference the index of the repeat group/ repeat group counter at this time? It seems that none of the position(..) operators that I called were able to execute in Survey123 even though my work in other ODK collect/XLSform converters.
"ReferenceError: position is not defined in expression: position(..)"
The end goal I am trying to accomplish would be to dynamically reference external data within a repeat group of a varying number of iterations. Such that the form could be pre-populated with existing data.
Thanks,
Max
