Hello,
I need help with some actionscript!;)

my slideshow is almost workin but i am getting an error message saying:

1084: Syntax error: expecting rightparen before SimpleButton.

Here is what my code looks like:

stop();
//next button
SimpleButton.addEventListener(next_btn.onPress=function(){
if(studio_art1._currentframe==studio_art1._totalframes){
studio_art1.gotoAndStop(1)
}else{
studio_art1.nextFrame()
}
}

//last button
SimpleButton.addEventListener(back_btn.onPress=function(){
if(studio_art1._currentframe==1){
studio_art1.gotoAndStop(studio_art1._totalframes)
}else{
studio_art1.prevFrame()
}
}
