Simple link to a pdf

I tried this but it comes up with errors

my_btn.addEventListener(MouseEvent.CLICK, onClick);
function onClick(e:MouseEvent):void{
navigateToURL(new URLRequest("http://www.test.com/pd.pdf"), "_blank");
}

This is probably an easy one for you experts

what is the error? post the trace out and it would better help give you some direction.....

[public function transitionIn():void]

Im putting my code in override public function transitionIn():void
 
1180: Call to a possibly undefined method navigateToURL.       navigateToURL(new URLRequest("http://www.test.com/pd.pdf"), "_blank");
1180: Call to a possibly undefined method URLRequest.        navigateToURL(new URLRequest("http://www.test.com/pd.pdf"), "_blank");

You have to import that methods.
import flash.net.URLRequest;
import flash.net.navigateToURL;

hah fantastic it works now, the only issue is it doesnt change pointer to hand like this

It just stays like this

my_btn.buttonMode  =true;
