Guys, I’m stuck with this code  
I want to make a simple next and back button for an instruction page

so far this is what I have

back2\_btn.alpha = 0;  
back2\_btn.mouseEnabled = false;

back2\_btn.addEventListener(MouseEvent.CLICK,controlHandler);  
next\_btn.addEventListener(MouseEvent.CLICK,controlHandler);

function controlHandler(evt:MouseEvent):void {  
switch (evt.target) {  
case back2\_btn :  
prevFrame();  
next\_btn.mouseEnabled = true;  
next\_btn.alpha = 1;  
if(currentFrame == 1) {  
//if it is frame 1, disable previous button  
back2\_btn.mouseEnabled = false;  
//dim the button by making it transparent  
}  
break;  
case next\_btn :  
gotoAndPlay(currentFrame + 21);  
back2\_btn.mouseEnabled = true;  
back2\_btn.alpha = 1;  
if(currentFrame == 103) {  
next\_btn.mouseEnabled = false;  
next\_btn.alpha = 0;  
break;  
}  
}  
}

actually i prefer to do it using labels but i was expected to do it effectively,lesser code,lesser size,etc

can anyone tell me what’s wrong with the code?
