Advanced Button Problems

Ok well I got the button to work from this tutorial and the link and everything works, but I want the button to go to a frame instead of a URL. What is in red is what I am trying to change. The code is as follows:

stop ();
this.onEnterFrame = function(){
if(rewind == true){
prevFrame();
}
}
this.onRollOver = function(){
rewind = false;
play();
}
this.onRollOut = function(){
rewind = true;
}
[COLOR=red]this.onRelease = function(){
getURL(“http://www.toxiclab.org”);
}[/COLOR]
This is what I tried to replace it with but it did not work, is their another way to do this? Basically what I want to know is how would I go to another frame using this code?

[COLOR=green]this.onRelease = function(){
gotoAndPlay(7);
}[/COLOR]
Thanks for any help that follows.
