No problem. I did find the answer that OP was looking for in these threads, though:
- Choice filter not working on second loop of nested Repeat - #5 by tjaramillo
- Cascading selects in a repeat group & indexed repeat - #9 by A.N.M_AL-IMRAN
- Quick tech call: rectifying current() in choice filter
IMO this is a bug in PyXForm. If a choice_filter is used inside a repeat and targets another node in that repeat, the node reference should replace absolute pathing with relative, e.g. filter_list= current()/../TARGET_QUESTION
