How to setup tracking with prosper202, 7search and peerfly

Hi,
I've been trying to works out how to use prosper with 7search/peerfly but there are a few bit's I'm uncertain about, I was hoping for some help.

I have the following at the end of my campaign url in prosper:
&s1=[[subid]]&s2=[[c1]]&s3=[[c2]]

I have been trying to work out how the Simple Global Post Back URL works i.e
tracking202/static/gpb.php?amount=&subid=

in Peerfly I found the following but am not sure what needs to be included in the Simple global post back url:
%offer% The OfferID of the lead/sale credited.
%commission% The Commission you received for the lead/sale.
%subid1% SubID 1
%subid2% SubID 2
%subid3% SubID 3

I think you then need to enter the 7search variables ###KEYWORD###, ###AFFID### and ###RID### into prosper under the get links section in the tracking id section (shown below) but I'm not sure which variables go in which boxes and how the sections connect to the above, any advice would be appreciated. Thanks

Tracking ID c1:
Tracking ID c2:
Tracking ID c3:
Tracking ID c4:
