Google Analytics: Track/on release issue?

Google Analytics was able to track the “clicked” ads with html and track js, but it couldn’t track the “clicked” ads coming from swf. I use xml file to load data into swf and it appears successfully load everything except track. Is this on release code wrong?:

box.on (release) { 
//Track with action 
getURL("javascript:pageTracker._trackPageview(trackad[p]);");
getURL(link[p], "_blank");

appreciate any help in advance!
