Hello,

I have a group of students which need to make two surveys - one at the beginning of the course and the second at the end after 4 months. Both surveys are exactly the same - we just monitor if something changes

So basically they need to make the first survey where we collect all the required data and their user_id as a hidden field.

When they approach the second survey I want to prefill all fields with the values from the first one (based on the user_id)
So, if nothing changes, they just send the exact same answers as the first one. If not, they change only the fields where something changes.

I hope it's not too complicated

Thanks
