Randomize/shuffle array item without repeat actionscript 3.0

Question

i am creating a question and answer quiz using flash cs3 and actionscript 3.0.
i have a large array of question, i wish to put it into xml document
(can xml document be reside in the flash file itself?i thought ive seen someone did that.)
ok,my main problem is to shuffle the questions without repeat until all questions were asked. i have worked on this tutorial,and it does great shuffling without repeat. http://www.flashandmath.com/howtos/deal/
but,i wish to ask one question at once. i have looked into the option to shuffle frames, but i think about how can i count the score of the quiz at the end of it?
can anyone tell me the best way of doing this?
many thanks 

Answer 1

. i have looked into the option to shuffle frames,
you can`t really shuffle frames in flash, you have to tell the playhead of your movie to jumpp to a specific frame.
so if you have say 20 Questions that are ordered in 20 kjeyframes along the main Timeline. you will have an array o Numbers from 1-20 that is shuffled by a function like you mentioned above.
Then in the function that evaluates your answers that targets this aray as a pointer to where to go next.
The pointer could be a simple Number, that describes the position of one specific number in this array, like so:
//At the beginning of your quiz
var randArray:Array = [1...20];
var pointer:int = 0;
var points:int = 0;
var right:Boolean= false;
//in the function that evaluates your answer
function evaluateAnswer():void{
   if(right){
   points+=1;
else{
//don`t add Points
//this will choose the next frame from your shuffled Array
pointer++;
if(pointer<=20){
this.gotoAndPlay(randArray[pointer]);
else{
//when the last question is answered do something in a funtion that shows the result
showResult();
