Question about movie clip buttons help!

Hi, I am putting together a button from a movie clip using this kirupa lesson:

I have it all complete except that I don’t know how to target the button to goto and play a frame in the main movie. I don’t want “getURL”. Anyone have any ideas? Thanks so much!

This is the movie clip code:

//all this code is inside the complex button so you can stick as many as you want
//on the stage and all will work… they all will have this code in it…

stop(); // stop the movie clip from playing (stop button from growing, we want that when the mouse rolls over only

this.onEnterFrame = function(){
if(rewind == true){ //if rewind switch is set to true play backwards
prevFrame(); // play backwards

this.onRollOver = function(){
rewind = false; //set variable (or switch) that decides wether ot not to play backwards…
play(); // play this movie clip… (grow the button(tween));

this.onRollOut = function(){
rewind = true; //set or rewind switch to true so it will play backwards…

this.onRelease = function(){
