if you're using a document class ascircle, that should something like:
package{
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class ascircle extends MovieClip{
public function ascircle(){
init();
private function init():void{
stage.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
Circle.play();
// if you're adding code to the main timeline, you would use:
stage.addEventListener(MouseEvent.CLICK,clickF);
function clickF(e:MouseEvent):void{
Circle.play();
