Highlight box when rollover

programming flash
1

I am working on a flash menu and I have 3 boxes that when you rollover, the box moves up and loads a movie. I am trying to add another rollover that highlight the moving box when you rollover and then return to the original when you roll out. I have managed to color the box when you rollover but I would like to to outline it.

Here is the code that I have

on (rollOver) {
var colorful = new Color("_root.shapes");
colorful.setRGB(0x003366);
}
on (rollOver) {
loadMovie (“MOVAUTO.swf”, “containerclip”);
gotoAndPlay(1);
stop();
}
