Any Google Analytics experts? Help with EventTracking

I am trying to use the EventTracking feature on Google Analytics to track link clicks on a page where content is reloaded via an AJAX script.

I have modified the links to include the following code:

onClick="pageTracker._trackEvent('Artist', 'Visit', 'Artist Name')

Artist represents the category of event, visit represents the action, and artist name is changed on each link and represent the actual content loaded.

I did all of this on Sunday and I still haven't seen any events register in GoogleAnalytics. The article I read from Google made it seem like this was all one had to do, so I'm a bit stumped as to why I'm not seeing anything being reported.

The only thing I can think of is that I might need to modify the GoogleAnalytics code in my header to turn on EventTracking. Google's documents weren't too clear on that.

Anyone on here an expert in Google Anayltics?

BTW - I am using the new ga.js tracking code, so that is not the problem.
