Zoom In/Out

What I have is a map of the U.S. I want people to click on a state and have the US zoom into that state. While zoomed in to a particular state, they can click on a neighboring state and have it zoom to that state. An example can be found here:

This is exactly the thing I want, but in flash. I also found this in Kirupa and it’s exactly what I’m looking for, but there is no fla file. Could someone please help.

I think all I need is a simple script to zoom in and zoom out on a movieclip while telling the other movieclips to zoom relative to it.

Thanx
p.s. I really need this ASAP.
