I have looked over several posts and can’t seem to find this answer.  
Basically I have a \_mc that I am calling in from the library. When I get to the end of the clip I want it to advance the root time line to frame 3.  
This is the code I have at the end of the \_mc  
MovieClip(root).gotoAndStop(3);

This is the error I get :  
Error #1009: Cannot access a property or method of a null object reference.  
at introScene/frame91()  
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@44370ba1 to flash.display.MovieClip.  
at introScene/frame91()

Thanks for the help…
