1120 : 정의되지 않은 속성에 대한 액세스 clickBt

Question

Flash CS3를 사용하여 게임을 만들려고합니다. 아직 CS3에 새로 등장했습니다.
누군가 나를 도와주세요. clickBt이 정의처럼

Line 17 1120: Access of undefined property clickBt.

package { 
import flash.events.MouseEvent; 

public class StartScreen { 
    public var b:Bt; 
    public var ref:main; 

    public function StartScreen(r:main) { 
     ref = r; 
     startScreen(); 
    } 

    public function startScreen(){ 
     b = new Bt(); 
     b.x = 200; b.y = 200; 
     b.buttonMode =true; 
     b.addEventListener(MouseEvent.CLICK,clickBt);
