Hi Rhonda,
Ohh no, that is a pain! I’m sorry this happened, but glad the parent who edited the form didn’t mess the entire thing up!
The solution is in how you’ve shared the Form in the first place – you’ve shared it with parents as collaborators and effectively made the Form editable; whereas you really only want them to fill it in – make sense?
The video inside Google Sheets & Forms for the Office > Gathering Data > Introduction to Forms > Step 13 ‘How to send the Form to others’ will show you how to do this.
Unfortunately, you can’t undo what the parent over-wrote as there isn’t currently a Version History inside a Form – but at least the parent didn’t muck the entire form up in this case!
This Form would be a good one to share with others, as all schools have to do the Health Consultation Survey.
