Can't get SharedObject to work..

Basically I've created a score counting program in ActionScript 3, and I want to save the points when I close the program. But I don't understand why the code isn't working..

//The cookie

var store_stats:SharedObject = SharedObject.getLocal("store_stats")

stage.addEventListener(Event.ENTER_FRAME, flusher)

    function flusher (Evt:Event) {

        store_stats.flush();

        store_stats.data.player1stats = player1Score;

        store_stats.data.player2stats = player2Score;

    }

trace(store_stats);

//Game stats

var nummer1:Number = 0;

var nummer2:Number = 0;

var player1Score = 0;

var player2Score = 0;

var isDeuce = false;

var isBattle = false

And how to I write on the forum with code font?
