Im trying to create some class that will take two arrays of DisplayObjects, mask each item of one with the item on another with same index, create an array full of BitmapDatas and make each of those BitmapDatas draw the masked DisplayObject with same index, and return the array of BitmapDatas  
However i dont know why its not working

ActionScript Code:  
[FONT=Courier New][LEFT]\</p\>  
\<p\>[COLOR=#808080]_/_\</p\>  
\<p\>this class returns an array of BitmapDatas made of two other Arrays\</p\>  
\<p\>it masks one with the second and draws all to create the BitmapData\</p\>
