Hello, everyone!
I have this repeat part of my Survey123 form (1st screenshot), and I want to create a feature report using the template below (2nd screenshot). However, when I attempted to add the feature report template in my ArcGIS Online account Survey123 web to generate the report, I encountered the error below (3rd screenshot).
Does anyone encounter this error? Do you have any hint/idea on how to fix this one? I appreciate any suggestions. Thank you very much.
