Form submit not redirecting

Hi,

I am stuck on a form redirect. I setup this form: http://ynpn.org/phoenix/membership-application/. This form is linked to User Registration Addon, so they get logged in. But they are supposed to be redirected to: http://ynpn.org/phoenix/register/, which doesn't happen. They do get logged in and an email saying they registered. The Register page is where payment is made using the Memberhsip Plugin from WPMU. I've looked at all the settings and everything seems to be right. Any thoughts on what the issue could be?

Thanks!

The redirection is set in the form confirmation settings by selecting redirect and adding the URL to redirect. When the form is submitted, they do get logged in and sent an email with the username and password they just created, but they are still on the same page as the form. So it's not redirecting, just saying on the same page where the form that was just filled out in. Does this help?
