Hey Guys, A last resort before going bald from pulling my hair out! Hoping someone on the list may be a programmer and have worked on the Chorus (used to be telecom wholesale) B2B system into wireline. I'm able to work with all the WSDL's but one, the querytoolsservice.WSDL . For those that know what I'm talking about and have the SDK documentation, the portion of the SOAP SDK is 11.4, or anything in section 11. I would appreciated any assistance anyone may be able to provide, please email me directly and keep it off list. Many thanks in advance. Barry Murphy
