Using SharedObjects properly

programming flash

OK, I thought I was understanding how to use SharedObjects, but I guess I’m not. When trying to clean up/initialize variables in the object, I get this error:
TypeError: Error #1010: A term is undefined and has no properties.
at MethodInfo-89()
at Main/ClearScores()
at Main$iinit()
TypeError: Error #1010: A term is undefined and has no properties.
at Main/::frame25()

In my main document class, I define this public variable:

  var gameData:SharedObject = SharedObject.getLocal("saveData");//Store highscores and player data

here is the function that is causing the error:

 
  public function ClearScores():void{
   //scoreData.data.bests = new Array(["NoOne",0],["NoOne",0],["NoOne",0]);
   gameData.data.bests = new Array();
   gameData.data.totals = new Array();
   gameData.data.averages = new Array();
   trace(gameData.data.bests);
   ScoreReset(gameData.data.bests);
   ScoreReset(gameData.data.totals);
   ScoreReset(gameData.data.averages);
   gameData.flush();
   trace("GAME DATA:
"+gameData.data.bests);
   function ScoreReset(theScore:Array):void{
    var i:int;
    for(i = 0; i <= 2;i++){  //keep up to 3 scores
     theScore*[0] = "NoScore";
     theScore*[1] = 0;
    }
   }

Any help would be great. Thanks in advance.
