The thank you page link is not working on my form.

The thank you page link appears correctly on the form when I'm designing it, but when I submit a response to the form it says 'page not found'. The link should be: http://www.meetupuppervalley.com/thank-you-glass.html

That happens because there is a condition that will redirect to this page: http://www.meetupuppervalley.com/thank-you-glassblowing.html, after submission If Method of Payment if equal to "Pay by cash or check" or "Pay with credit card by phone (includes a processing fee)": 

Upon looking at your submission, that's what has been chosen:

So, the user will not be re-directed to your custom Thank You page link: http://www.meetupuppervalley.com/thank-you-glass.html, if any of those options are chosen. So, you might want to delete that condition.

Hope this helps, let us know if you have more questions.
