PDF form handling

Hello,
I'm trying to make PDF-fillable forms using Adobe Lifecycle Designer 8.0. I have no problem creating the forms, migrating them over to my web host, opening them, and filling them out. However, when I hit the submit button, I'm receiving error that the "page is not found."
 
This happens regardless of whether I use email or http submit buttons. I would prefer to use the http submit option if possible, as student users of my forms at my university do not have a default email program.
 
I should note that I have no problems creating forms in Dreamweaver and retrieving submitted data. However, I want to use forms made from PDF documents I've created in the past.
 
Thanks for any assistance you can offer.
