Put getURL to all mc on the stage

1

I would like to put getURL on all mc on the stage, I put the script like this

 
var _root.url_array:Array = new Array("url1","url2","url3")
for (var mc in this) {
   var i:Number = 0;
   if (typeof (this[mc]) == "movieclip") {
       this[mc].onRelease = function() {
            getURL("lingo: go to \""+_root.url_array*+"\"");
            i++;
       }
   }
}

the problem when I click on mc, it go to same url, how can I it different.

Thank
