In form builder this error appears for 2 projects I am working when I preview the form. The project was uploaded from a XLSform, although there were some errors in the form that required me to manually input skip logic and validation criteria. Any ideas on how to fix? Do not have any coding knowledge!
Welcome to the community @Bethany! Users generally face this sort of a loading error when there is a syntax error within the xlsform. To check if your xlsform is clean would you mind validating the same through this online validator. It should help you identify and fix the syntax error present within your xlsfrom.
If you however still face the issue, please feel free to share your xlsform with the community. The community would love to help you solve your issue.
