unable to retrieve the url endpoint

Hi guys..

we have made the move to C# for a bunch of business logic.. exposing it as a c# web service.

in test, its consumed great.. soapUI makes all behave correctly. We have a delphi application that runs a part of the system, and we are swaping this section, to use the c# web service..

I think I have chased this issue down to a version thing..

when I set the protocol to use 1.1 using the dafault port name I get an error like

"object ref not set to an instance " lists the file location of service.cs and tells me its line 106

which is anoying, cos it works for two other clients, and the soapUI,
also, its a micky mouse line

102 [WebMethod]
103 public SummaryData[] GetSummaryData(string SearchTerm)
104 {
105
106 string[] SplitSearchTerms = SearchTerm.Split('|');

----

So i tried to change the protocol of the delphi to 1.2 again calling port servicesoap and got the same error.

----

the third try, was protocol on 1.2 but calling port servicesoap12 - I get an error like this

unable to retrieve the url endpoint for service/port 'service'/'servicesoap12' from WSDL http://192.168.168.15/ws/service.asmx?WSDL

I have tried so many things, and had to start again, but unfortunatly, got the same set of errors!.. any light on the issue would be greatful. I am using .net FW2

Aber..
