I have been trying to develop a browser-based infopath2007 form that submits
to our SQL database.  I understand that a browser-based form cannot submit to
a database directly, but can do so via a webservice.  I am attempting to set
this up by referencing the following page:
http://blogs.msdn.com/infopath/archive/2007/01/29/submitting-to-a-database-via-w
eb-services-in-infopath-forms-services.aspx
(which gives step by step instructions), and have been successfull in setting
up everything descirbed in the article.  However, once I attempt to create a
form based on a web service I get an error while going through the wizard.  
The error states:

The SOAP response indicates that an error occurred:

Server was unable to read request. ---> There is an error in XML document
(1, 406). ---> Input string was not in a correct format.

I only modified the code where it states to do so.  The part of the code I
modified are for the database connections and webmethods as described in the
article.   I am new to visual C#, so please let me know if more info is
needed.  Thanks.
