Hi friends.  
I have this wonderful modified Multiple Choice Quiz coded in AS2.  
It chooses from 14 questions from en xml file and randomly picks 5 questions  
everytime you run the quiz. That works fine.  
The thing I would like to improve is that now I do get “duplicates or repeats”!  
F. eks questions 2 appears twice in a set. So I would prefer to have only unique random and  
different questions everytime the quiz runs, but I dont have the expertise to solve this.  
Can you help?  
The code that randomises looks like this:  
// Randomize order  
for (i=0; i\<quizItems.length; i++)  
{  
var indexToSwap=int(Math.random()_quizItems.length);  
var temp=quizItems[indexToSwap];  
quizItems[indexToSwap]=quizItems_;  
quizItems\*=quizItems[indexToSwap];  
}  
You can find the complete code in Frame 1 in the attached .fla.  
I would appreciate any suggestions and improvements - THANKS!
