AS3 expanding banner

To help us with our projects we completed a tutorial on an expanding Flash banner in AS3. Here be a link.

During this we used masking and frame labels. Both of which I have never really used beforehand. We also had to use DreamWeaver to fondle with some HTML to display it.

Here's a dropbox link to see it. Bambi. Well, I can't show it because I don't have any real hosting, my bad.

This is the hot spot which triggers the animation (Which is a tween) to play. Essentially when you mouse over the hot spot it goes to and plays from a frame, it then does the same when you remove the mouse but to another frame, both the start of a tween making it look like a smooth animation.
