OSB Branch Problem

Question

Hi there,
I have created a set of Business Services backed by SOAP services and then Proxy Services for each (3). The three Proxy Services are then configured in a new "Wrapper" Proxy Service which uses one of the Request Parameters to do a Branch. The Branch will then drop to a route/routing for each original Proxy Service backed by a Business Service. This is a content based routing scheme.
I have successfully tested the 3 Proxy Services. When I run the "Wrapper" service the OSB server has an error:

My questions:
#1) - any ideas on the way to fix the error ?
#2) - When I can do a basic invocation for the Wrapper Proxy Service I will then need to map the "Wrapper" Request (parameters) to the individual Proxy Request that is routed to (they have different WSDLs / signatures) AND then do the mapping on the Result (Response). I was planning to do an "Assign/Replace" but have not been successful yet. Any ideas on this?
All hints are appreciated.
Thanks,
David.

Hi there,
I have solved everything but the Branching Issue. I added Branching at the end and it causes an Error of "UNBOUND CURRENT NODE". You can see my Proxy Service below:
