Getting soapMapper error in web service call

[sessionsa]

I have used the MS Soap kit 3.0 and have been able to initiate the webservice, using the following code, and the web service completes corectly. However, I am getting an error... "SoapMapper:Restoring data into SoapMapper string failed HRESULT=0x80070057: The parameter is incorrect. - Client: Unspecified client error. HRESULT=80070057: The parameter is incorrect."

This happens at the "cRetVal = soapClient.process("GREC1,$#$CV1438813B")" line of code. Any ideas?

Function...

'Create the SOAP Client
Dim soapClient As MSSOAPLib30.SoapClient30
Set soapClient = New MSSOAPLib30.SoapClient30
'soapClient.ClientProperty("ServerHTTPRequest") = True

'Initialize the soap client and pass the URL for
'the WSDL file as a parameter
Dim cWSDL As String
cWSDL = "

http://discovery.mfia.state.mi.us:9...llTPRprocessSWSS/1.0/BullTPRprocessSWSS?wsdl"

Call soapClient.MSSoapInit(cWSDL)


'Call the Execute() method and display the results
Dim cRetVal As String
cRetVal = soapClient.process("GREC1,$#$CV1438813B")
MsgBox (cRetVal)

End Function...
