Created a Custom Application Form for an adult school, removed all “parent” fields and a few other fields. I also changed some labels.  
When I entered sample enrollment data, filling out all the fields, I keep getting the following error message:  
_ **”Your submitted data has been saved, however one or more required fields were incomplete. Please check the highlighted fields and submit the form again.”** _

Attached are screenshots of all the 5 pages that’s in the form.

I’m wondering if there are fields that are mandatory that I didn’t include in the form.
