Problem in calling function

package {
import flash.display.;

public class Title extends MovieClip {
        startButton.addEventListener(MouseEvent.CLICK, startButtonClicked);


    private function startButtonClicked(mouseEvent:MouseEvent):void {

the code works fine , but actually i want the “Object(parent).showHighScores();” to be load automatically without clicking the button (auto call the function once the page loaded), i tried use Event.Enter_frame but it wont stop running, can u help me ?
