Great to know that it worked with ODK Collect. By the way, which version of the KoBoCollect android app are you using? Maybe you could stick with the ODK Collect if it’s working fine for you.
@Kal_Lam unfortunately the same error message comes up again although enumerators use ODK collect. It is imperative data collection, I don’t know how to resolve the problem
@dheniardhian, could you share your xlsform so that the community should be able to test it and help you out to see if there are any syntax issues present?
Once you fix them up, could you try to see if this solves the issue? If not please feel free to share the updated xlsform again. We could then go through the next round of investigation.
