Problem With Transition Tutorial Help Please

programming flash
1

Ok, i’m following these two tutorials…
http://www.kirupa.com/developer/mx2004/transitions2.htm
and
http://www.kirupa.com/developer/mx2004/button_effect.htm

Now, i’ve assigned the code on the transitions tutorial onto the button, so it looks like so…

 
stop(); 
  
this.onEnterFrame = function(){ 
if(rewind == true){ 
prevFrame(); 
} 
} 
  
this.onRollOver = function(){ 
rewind = false; 
play(); 
} 
  
this.onRollOut = function(){ 
rewind = true; 
} 
  
this.onPress = function(){ 
if (_root.currMovie == undefined) { 
_root.currMovie = "portfolio"; 
container.loadMovie("portfolio.swf"); 
} else if (_root.currMovie != "portfolio") { 
if (container._currentframe >= container.midframe) { 
_root.currMovie = "portfolio"; 
container.play(); 
  } 
 } 
}

Now, when i click on the movieclip/button, it wont transition, the about.swf just stays on the page. What am I doing wrong here?
