Help Parsing XML Mesage using PeopleCode

Hi all,

 I'm new to web services and XML but was able to consume a WSDL and call the web service successfully.

I'm now trying to parse the XML message I’m getting as a response and to extract values i need and having issues Parsing the response.  Below is what I have done and the code from my Test AE.  Basically I’m trying to navigate to the "Results" element in the response and then use GetChildNode to get child nodes and then use FindNode to find elements and their values.

Here is the WSLD I consumed to create the web service in PS.
