Javascript error... Need a little proofing

I’m trying to set up a pop up window within Flash off a geturl statement

The window is successfully made but I’m getting an expected ‘)’ error. Anyone see where it goes?

on (release) {
var instance = this.link2;
getURL(“javascript:window.open(‘http://consumer.bst.bls.com’,‘Jan’s Message’,‘width=570,height=650,top=’+((screen.height/2)-(NaN))+’,left=’+((screen.width/2)-(NaN))+’,toolbar=no,scrollbars=no,resizable=no,menubar=no,status=no,directories=no,location=no’);%20void(0));”);

}

Thanks!
