What happens if I remove a section that has a field which is used in conditional logic?
If you try to remove a section that contains a field used in conditional logic, you will see an on-screen warning message explaining that removing the section will result in the conditions from the field being deleted.

The warning also lists the sections that are conditionally displayed from a selection or an input in the field or fields that are controlling the display of another section or sections.
You can then choose to retain the section by clicking No, go back, or to delete the section and all related conditional logic by confirming Yes.
