im using this code:  
stop();  
dna10\_btn.addEventListener(MouseEvent.MOUSE\_DOWN,mouseDownHandler2);  
function mouseDownHandler2(event:MouseEvent):void  
{  
nextFrame();  
}

throughout my frames in flash cs4 but it keeps coming up with 1021: duplicate function and i know i have to change the function name but how do i change the function name?
