Don't worry. It has nothing to the form we have been working on. LOL!
I am back to working on the previous form which was working until I added a few things. I checked the script andI changed the form name but it isn't working. I think it must be something simple.
I worked on correct form and in backend preview all works ok for me.
Please send me again your frontend link, because when I click on it I see only this:
Error
You are not allowed to add new records
and form is not shown
