Newbie-can anyone help? shrinking and growing button when rollover

Hi folks,

I’m a newbie… and have a problem. Basically I know what I want to happen, but I need some genius to convert my lay-terms into action script (mx 2004) or whatever works.

Ok, I have a button that I want to smoothly grow when I rollover it. When I rollout of it, it then needs to shrink back to it’s original size. But… This is the tricky bit! -How do I make it so that if I rollout half way whilst its getting larger, it begins to shrink from that point on and doesn’t jump/jitter?

I need to set a limit to the size that it grows to e.g to a maximum 120x120px.

Any help would be much appreciated.
TIA
