MC Complex button pop up window

Hi,

I have created a few set of complex button using this MC complex button tutorial .

Was wondering if it’s possible to change this:

//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");
}

The getURL part, into a popup window? I tried many ways by combining different tutorial’s script to get the effect, but it does not work.

Can anyone help?

[edit] - I want a specific size pop up window. Not really sure how to make the javascipt works, cause I tried and it didn’t work.

Thanks alot.

Regards,
Karen.
