I just did something strange(for me):

var b:Number = 10, a:Number = 20, c:Number = 30;  
var myArr:Array = [a, b, c];  
trace(myArr) // return 20, 10, 30  
b=99  
trace(b) // return 99  
trace(myArr) // still return 20, 10, 30

so I realized that an Array doesn’t update itself, so I need a function to update it, but how?

thanks
