Help, please!

Hi guys,

I have this script for the buttons on my site:

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.kirupa.com”,"_blank");
}

can someone tell me how to make the buttons gotoAndPlay a frame on release. I tried replacing the getURL with gotoAndPlay, but unfortunately it didn’t work at all.
Somebody help, please…
