Service Reference return data not populating return object

Using a complexType as the return value defined in the wsdl.  Visual Studio 2013 was able to create the proxy class and the complexType class objects for the complexType using the Add Service Reference option.  When I call the routine to request server data I get no errors until I try to access a class variable for the complexType data that I expected to be returned..  I then get this error message "Object reference not set to an instance of an object." I assume I should be able to return back multiple records in XML format back to the client and the client should parse this out into the class object that was created from the wsdl.
