HELP: clickTag Code

programming flash
1

Hi, I only got this clickTag code from GOOGLE themselves but is giving me some errors when I CHECK the AS.

URL REFERENCE: http://support.google.com/dfp_premium/bin/answer.py?hl=en&answer=1085684
(at the bottom of the page, choose AS3)


MyButtonClip.addEventListener(MouseEvent.MOUSE_UP, function(event: MouseEvent): void {
var sURL: String;
if ((sURL = root.loaderInfo.parameters.clickTAG)) {
navigateToURL(new URLRequest(sURL), "_blank");
}

The errors says:

Scene 1, Layer 'Layer 96`, Frame 1, Line 5  1084: Syntax error: expecting rightparen before end of program.

thank you
