>I am using VFP7 and have registered the web service in Fox and used intellisense to generate the neccessary code ie

>loPOSService = loWS.SetupClient("MyURL?wsdl", "POSService", "POSServicePort")
>
>The program then checks that this has worked okay and doesn't go any further if it hasn't
>IF VARTYPE(loPOSService) <> "O"
> RETURN .f.
>ENDIF

>The next line of code is to create another object that contains the response from one of the methods of the service

>This is the line that gives the occassional error.
