What version of ODK Collect are you using?
Is it a problem with just that one form? If so could you share it here?
Hi @ssraza
The problem seems to be in row 9 and 10. There in calculations you use:
Row 9: search('n_districts', 'matches', 'province_id', ${province_id})
Row 10: search('n_tehsils', 'matches', 'district_id', ${district_id})
Why did you place it there? The options for select questions you use are defined in the choices sheet. The search functions are used to load choices from external csv files.
