Welcome, @mikefreeman.
Happy to clarify.
The var website = $form.find('input[name="website"]').val();snippet applies to the original poster’s use case. The code will retrieve the form’s website field value with jQuery and the rest of the code @derekcavaliero provided will append this website value to the redirect URL of http://www.domain.com/simulate.php.
If you’re looking to append all the form field data to the redirect URL, go with the code in the soluton to this thread.
Be aware that you’ll have to set the portalId and formId as well as change http://www.yoururl.com? to your desired redirect URL.
