For ease of testing this form is set to allow multiple submissions by each user. For real you would want one submission which submitter can edit.
Submitters cannot see the project number field. Use "view recent submissions" to edit those.
The student side view of this data is at the "testpage data" sub-page (but could be anywhere) which is intended to be student facing.
Use "edit form" to also get at the data selection shown in the "form dataset" and edit what students can see.
