Issue with deploying an XLS form Error 500

Hello everyone, I am experiencing an Error 500 issue and unable to deploy a form. See image below

Hi @abalo_frederic_18 and welcome to the community!

Can you validate your form in here to see if there are any syntax issues?

Thansk you so much. It is okay. There was a group withouth children

Your Error 500 was caused by a group in your XLSForm that had no children questions. Ensure every group or repeat has at least one question inside. Validating your form with getodk.org before deploying will catch these issues.
