ActionScript 2.0 :: From Buttons Playing 2 Movies That Display Text

I am creating a website that teaches kids about the about the brain and I am creating a website very familiar to this one, [URL]. I created one flash file and drew the background for where the text will display. Next I created several movie clips for each of the brain parts and I placed an invisible button over each of these movies, e.g., I told the button, "cerebellum_button" to play the movie "cerebellum_mc." which includs text.

I feel that my code is redundant because I am having to create an invisible button for each animated movie clip which plays a movie clips with text. Is there a way that I can centralize all of the text in the project then call it from different buttons? My aim is to have the user roll over the brain part, have it animate, and have it display the text that explains what that brain part does.

cerebellum_button.onRollOver = function(){
cerebellum_mc.gotoAndStop("turnon");
} cerebellum_button.onRollOut = function(){
cerebellum_mc.gotoAndStop("turnoff");
