Hi!

I'm trying to build the following scenario using Cover Page:

1. User enters an email on a page with a sign-up form.
2. Once submitted, the user is redirected to a /thank-you page, and the entered email address is set as a URL parameter: /thank-you?email=<user_email>.
3. We then use that parameter on the /thank-you page.

While I've managed to make this work using a regular page and form, the scenario doesn't work with Cover Pages. I tried to add the following code to the POST-SUBMIT HTML form option and the Advanced page option. But it doesn't work (no errors, so I think it might be ignored).

Can anyone advise if there is a solution, please?

###
<script>
document.addEventListener('DOMContentLoaded', function() {
  var form = document.querySelector('form[data-form-id="123456"]'); 
  
  if (form) {
    form.addEventListener('submit', function(event) {
      event.preventDefault(); // Prevent default form submission
      
      var email = form.querySelector('input[type=email]').value; // Get the value of the email field
      var redirectURL = '/thank-you?email=' + encodeURIComponent(email); // Construct the redirect URL with email as a parameter
      
      YUI().use('node', 'squarespace-form-submit', function(Y) {
        (new Y.Squarespace.FormSubmit(form)).submit({
          formId: '123456',
          collectionId: '',
          objectName: '',
          redirectUrl: redirectURL 
        });
      });
    });
  }
});
</script>

If your code worked on another page and on this not it might be because the Post Submit HTML only supports HTML lately.
