Button Question

OK…
I made a button out of a MC using this 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.thesite.com/"); 
} 

I’m happy with the result. Is there a way to use this code to “loadmovie” say from a container? I tried putting this in place of the “onRelease” function (I changed it to an “if” statement):

if (_root.currMovie == undefined) {

_root.currMovie = "news";
container.loadMovie("news.swf");
} else if (_root.currMovie != "news") {
if (container._currentframe >= container.midframe) {

_root.currMovie = "news";
container.play();

}

}

}

If anything, this serves to show what I’m trying to get it to do.
Thank you!
