ActionScript Problem

Hey All,
I have a little problem with my scenario. I am asked to create like a little flipbook with the capability of zooming in and out (to see bigger fonts). so i have created text inside a Movie clip. I’ve also created a zoomin and zoomout button. Now the current setup is that on the zoom button on (release) the scale values on the instance name of MC’s will increase which fakes the effect of the text getting bigger. but the problem is if i go to another frame, the MC does not inherit the action last applied but goes back to it’s default size.

any idea on how i can keep the action applied to everything until it the zoomout button is pressed?
