Hi, I have a class file that contains a for in loop. basically there are 50 states (movieclips) on the stage and here is what I have:

```auto
public var statesArray:Array = ['alabama_mc', 'alaska_mc', 'arizona_mc', 'arkansas_mc', 'california_mc'];
    private var states:String;
    
    
    public function Delegates() {
        
    //all of the state movieclips need to be alpha 0.
    for ( states in statesArray ) {
          //this[states].property = value;
          this[states]._alpha = 0;
        trace(states);
        trace(statesArray[states]);
         }

```

I don’t think I understand enough about arrays or for in loops to understand why this isn’t working… it traces the array, but not statesArray[states], and it doesn’t change the alpha of anything.

Please help! thanks!
