I have run the WebService Wizard for invoke the WSDL,and making the below script to pass the Parameters.

Dim UppWebService
LocalParameter("GenereerUitingOrder") = WebService("UppWebService").GenereerUitingOrder("T ype",20)

"While execution this i am getting error of
The GenereerUitingOrder operation call failed.
The .NET Framework 2.0 WSE 3.0 toolkit returned the following error:
Soap error:
Message: Server was unable to process request. ---> Object reference not set to an instance of an object."

Can you please clarify me...Which object i have to define.

Thanks in Advance,
