it looks like the problem is with the page you are sending the user to after the upload and email occur. The target page seems to have some problems and it will give errors when you try to go to this page by itself:
It seems that the Upload and email are occurring successfully as it is trying to send you to this target page afterwards. You can check it out by updating the go to page in the Universal Email. You should have it go to a new page that just has a message on it so you will know when you get there. You should then work out any issues with the email and upload after you have it redirecting like this. Post back if you have any more questions or if you encounter any further problems.
