Okay, so you have not used any code on your page, so you shouldn’t really be asking for help through the Wix Corvid Forum then as this is for all code related issues on your site. Since you have no code on your page then there is no issue with that.
So, as it is simply through the Wix Editor itself, you would be much better suited going through Wix Support themselves as they will be able to look at your site and tell you where you are going wrong.
You can either put in a ticket to them.

Or you can call them and speak to them directly.

However, depending on what your form is setup as, have a look at a simple tutorial about user inputs and setting up a form etc.

Also, remember that there is always the Wix Support pages that you can go to for help about anything in Wix too.
