Hi Shell,
Website on the address provided requires certificate for identification... :(
Update: Nevermind, wsdl is accessible without identification. I'll try to get a look...
Update2: According to my experience, VBScript is the worst choice for WebServices tests in TestComplete. The reason is that when you do negative testing (i.e. provide WebService with wrong data), an exception is usually returned from the call. You can handle it in VBScript using On Error Resume Next and On Error GoTo 0 statements, but they are really inconvenient and clutter test code a lot.
So, unless you have some good reasons as for VBScript, I would recommend to consider either DelphiScript or JScript.
