InfoPath Dev

I'm trying to subit a form to sharepoint using a data connection.  Additionally, I have set the file name as the contents of a field on the form.  When I submit the form, I get the following error: 

InfoPath cannot submit the form.
An error occurred while the form was being submitted.
The form cannot be submitted to the following location:

The folder does not exist.

 The folder location is correct, so I'm puzzled why this isn't working.  Any thoughts?

Was the sharepoint location an existing forms library or did you create a new one when you published the form?  I have had issue when using an existing location.  I would publish again to a new form library to test.
