Hi i am a beginner in actionscript coding and i am getting the error below when i click the “new game” button :

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at aircombat1\_fla::MainTimeline/moveMyfighter()

Can anybody tell me what the problem could be ?

you can see the movie here : [http://www.myholidays.dk/flash/finalproject/aircombat1.html](http://www.myholidays.dk/flash/finalproject/aircombat1.html)

My code look like this :

stop();  
scoreDisplay.text=score.toString();  
timeDisplay.text=seconds.toString();  
Mouse.show();  
myfighter.removeEventListener (Event.ENTER\_FRAME, moveMyfighter);  
enemyTarget.removeEventListener (Event.ENTER\_FRAME, moveEnemy);  
newgame\_btn.addEventListener(MouseEvent.MOUSE\_DOWN, startnewgame);  
var mySO:SharedObject;  
mySO = SharedObject.getLocal(“myfirstSO”);  
save\_btn.addEventListener(MouseEvent.CLICK, saveText);

function saveText(e:MouseEvent):void  
{  
mySO.data.myText = savegame\_txt.text;  
}

if (mySO.data.myText)  
{  
savegame\_txt.text = mySO.data.myText;  
}

function startnewgame (event):void{  
gotoAndPlay(“intro”);  
}
