[flexcoders] Randomizing Array (from actionscript cookbook3 and other places)

[{reduxdj}]

I am getting an error with the following code

TypeError: Error #1006: value is not a function.
    at com.me.data::PictureProviderXML/::handleComplete()
  

function randomSort(a, b) {
        return Math.random()>.5 ? -1 : 1;
        }


var numbers:Array = new Array();
              
                   for (var n:int=0;n<photos.length;n++){
                       numbers[n] = n;
                   }
                   numbers.sort(randomSort);


any ideas, it looks like I am using this properly any ideas?

Thanks,
Patrick
