Simple Button Question

Hey guys, I just finished making some buttons using the kirupa “Complex Button RollOver/RollOut Effects” tutorial. Now my question is, what line of code do I use to control what scene my movie is at.

Here is the code

//stop(); 
  
this.onEnterFrame = function(){ 
if(rewind == true){ 
prevFrame(); 
} 
} 
  
this.onRollOver = function(){ 
rewind = false; 
play(); 
} 
  
this.onRollOut = function(){ 
rewind = true; 
} 
  
this.onRelease = function(){ 
getURL("http://www.kirupa.com","_blank"); 
}

As you can see I need to change the “getURL(“http://www.kirupa.com”,”_blank"); to something that will change my main movie to a specific scene. Keep in mind this action script is set inside a movie clip.

Thanks in advance.
