I'm following the instructions at https://www.google.com/support/googleanalytics/bin/answer.py?answer=55532 to track my customer on the e-junkie 'receipt' page. When I add the one line they show in bold, my cart becomes a full-screen tab in Firefox, instead of the floating page above the dimmed out shopping page (which, of course I love).
Am I doing something wrong? Is there another technique I should use?
