Form does not work

Hi,
I have created a custom registration form for visitors to my website and I would like to a. store their data on a database and b. redirect them to another page after. I have tried to do this using input boxes and buttons and linking them to a database, as well as another page for redirect and everything looks good on paper. However, once I preview the page to test it I am not even able to enter inputs in the fields and clicking on the button does nothing.

Any clue or experience with what seems to me like a ‘lag’ from Wix?
I have also re-done the table multiple times and opened it on preview in different browsers

Thank you
