S.O.S project stuck on this issue...

Hi, I’m really stuck on this one issue that I can’t figure out on my own and I’m hoping someone would be happy to help me figure it out?

I posted a question recently about the issue (here: https://www.wix.com/velo/forum/community-discussion/how-to-popluate-text-elements-after-form-submission ). But after trying to figure it out I’m wondering if I should be using the wix-storage session API rather than currentUser because the site doesn’t have a members functionality, so I would need to be able to retrieve the last item submitted to the dataset by the website user even though they are not logged in.

Since changing things to try and fix it another issue has also occurred and it’s not even filling out all of the fields. No errors are being returned so it’s nothing to do with incorrect syntax by the seems of things.

I’ve been trying to work out how to sort it but I’ve hit a massive dead end, so any help would be amazing!
