Iframe question

[vood0o]

I have this code line : <iframe scrolling="no" style="border:0;width:300px;height:250px;" src="http://www.asdacz.com/banner.php"></iframe> Can I add in iframe after src, onClick=”_gaq.push(['_trackEvent', 'External Link', 'Twitter Link', 'Follow Us - Words']);”?? Or I have to use this code line:<a href=”http://twitter.com/impactmedialtd” onClick=”_gaq.push(['_trackEvent', 'External Link', 'Twitter Link', 'Follow Us - Words']);”>Follow Us</a> in this last line i can not see where i can put the src , as this is php file is a banner and i want to use it on an external website.
