Tracking URL in CS3 Banner

Hello everyone,
I created a simple banner with a button that when you mouse over it changes a different color and some mild math coding to make snow fall in the front. I have used this actionscript to add URLs to previous banners:

[COLOR=blue]on (release){[/COLOR]

This is the URL that is giving me trouble:

When I plug in the URL I get errors and it doesn’t work. Can someone please help me with this? I would greatly appreciated.
