	function TetrisHighScores(){
	  if (!sLevel.pflag && sLevel.Blocks != undefined && !sLevel.ToStop)
	    TetrisPause();
	  sHighScores.gotoAndStop("Loading");
	  var self:Object = this;
	  dataProvider.getUsersRating(function(success:Boolean){ // limit == 10
	    self.sHighScores.gotoAndStop("HighScores");
	    if (success) {
	      trace(this);
        var txtUserNames:TextField = self.sHighScores.txtUserNames;
        var txtScores:TextField = self.sHighScores.txtScores;
        
        txtUserNames.styleSheet = self.style_sheet;
        txtScores.styleSheet = self.style_sheet;
        var scores:Array = new Array();
        for (var fNode:XMLNode = this.firstChild.firstChild; fNode != null; fNode = fNode.nextSibling) {
          var user_id: String;
          var user_name: String;
          var score: Number;
            for (var cNode:XMLNode = fNode.firstChild; cNode != null; cNode = cNode.nextSibling) {
              switch (cNode.nodeName){
                case 'user_id':   user_id = cNode.firstChild.nodeValue;         break;

              }
            }
            scores.push({user_id: user_id, user_name: user_name, score: score});

        for (var i:Number = 0; i < scores.length; i++)

          txtScores.htmlText += "<p>" + scores[i]['score'] + "</p>";
        }
      } else {
        self.sHighScores.txtUserNames.htmlText = "Connection failed.";
      }
	  });
	}
