We are trying to set up integration with an external webservice.  We seem to be getting pretty close, but it looks like something is still off in our WSDL.  When I try to do the callout, I get this:

FATAL_ERROR|System.CalloutException: Web service callout failed: Unable to parse callout response. Apex type not found for element http://ILRequestService/ILRequestServiceResponse=ILRequest

I suspect it has to do with the 4th line of the response.  It's like the APEX parsing doesn't know what to do with that line.  Seems like it might be namespace-related, but I don't know what to change.  I've tried messing around with the WSDL to make elements "qualified" instead of "unqualified", but that did not seem to help.  If anyone could give some insight on this, it would be much appreciated.

The actual method I'm using is getILRequestObject.

Below is the relevant info:
