WebReference & WebService intregation with NAV

  

Hello,

 I would like to know if anyone has used a WebReference to "communicate" with a webservice created in NAV? I use the EnhancedWebReferences extension to connect (password\username) to the webservice, however when I fill the record (entry parameter of action GetXML) and use action GetXML I got an error:

The code:

Regards
