[SIZE=4]Hello  
I have a question about array  
if I have the following array for example:  
letters=new Array()  
letters[0]=“a”  
letters[1]=“b”  
letters[2]=“c”  
how can I pick a random element from above array without repetition?  
If I use random.math() function , I will get a random element but with repetition.  
to explain my idea in more details:  
i have button(b) and a dynamic text(t)… i want **one** and only one **random&unique** element from the array appears in the dynamic box(t) every time i press the button(b)  
Note: I tried to use shuffle array that i found in some websites but the problem is that all elements(a,b,c) appear in the dynamic box in the same time.  
i am really confused!  
any help will be appreciated[/SIZE]
