Hi guys  
I am getting reference error which is breaking my code. In my code i have drag gable movieclip which when crossed some coordinates is going to call external UIloader (containing external SWF) on the main stage. I can create multiple instances of UIloader by dragging same movie multiple times.(I am providing the option of dragging and dropping movieClip as well as UIloader too). Now when i am trying to drop movieclip on already created UIloader I am getting this error which is breaking my code. “ReferenceError: Error #1069: Property index not found on flash.display.Stage and there is no default value.”

Actually I have 2 drag and drop functions(on mousedown and mouse up) in my program. One for movieClip drag& drop and other for UILoader drag & drop. It seems like when i am dropping my movieclip on already existing UIloader, drop function of UIloader ( instead of MovieClip) has been called . I am not sure how to fix that.  
Any help will be highly appreciated.  
I have made everything in AS 3.0 without my custom classes. Attached is the code to make things little clear.  
Thanks
