Biztalk Integration with Commerce Gateway

When configuring the Biztalk Partner Setup for Biztalk 2004 what should be put in the Destination Address. I would like the xml document sent directly to Biztalk or if that isn’t possible to a file location so that Biztalk can pick it up. Also when choosing the Transport Type of CommerceGateway in a Receive Location in Biztalk 2004 what should go in the Address (URI) as when you click on the elipse it just shows CG://
