Array headache

1

Im pretty much new to arrays and its killing me to figure some stuff out. I have the following script on the main timeline in my movie

Array.prototype.shuffle=function(){
   for(i=0;i<this.length;i++){
      var tmp=this*;
      var randomNum=random(this.length);
      this*=this[randomNum];
      this[randomNum]=tmp;
   }
}



// USAGE:

arr1=["a","b","c","d","e"];
arr1.shuffle();
trace(arr1);

much thanks to sephiroth for it. Anyways, i created a movie clip with a dynamic textbox in it which i was hoping could pull one of the values from the array. How do i do this?

I uploaded the fla so hopefully one of you guys could tell me where im going wrong
