Error that I don't understand

Question

CODE:
package
import flash.display.MovieClip;
import flash.events.Event;
public class ElClickerino extends MovieClip
  public var screen_mc:Screen;
  public function ElClickerino()
   startGame();
  public function showGame( e:Event )
   removeChild( screen_mc );
   screen_mc = new ScreenGame();
   screen_mc.addEventListener( ScreenGame. WIN, Game );
   addChild( screen_mc );
  public function winGame( e:Event )
   removeChild( screen_mc );
   screen_mc = new ScreenWin();
   screen_mc.addEventListener( ScreenWin.PLAY_AGAIN, restartGame );
   addChild( screen_mc );
  public function restartGame( e:Event )
   removeChild( screen_mc );
   startGame();
  private function startGame()
   screen_mc = new ScreenTitle();
   screen_mc.addEventListener( ScreenTitle.PLAY, showGame );
   addChild( screen_mc );
error:
1119: Access of possibly undefined property WIN through a reference with static type Class.
1120: Access of undefined property Game.

Answer 1

There is a space before WIN in reference to ScreenGame.WIN constant inside showGame function. It is causing the first error.
The second one is caused by the same line of code - you have not definded Game function.
