A/B Testing - Google Analytics Connection

Hello all!
I have set up a/b theme testing plugin and it works fine. I see that the cookies are set, and everytime I delete the cookie through Firebug the theme rotates.

What I don't see, is the stats appearing in Google Analytics. I don't see any goals set up and when I go to "Custom-Variables" or "User Defined" it's just empty.

Is the plugin compatible with the new version of Google Analytics?
Where should I put the analytics key? Header, footer or it doesn't matter ? (currently I have it in the footer)

Thanks a lot
Panos
