TypeError: Error #1034: Question


i have created a simple movie clip of a blue circle on my first layer but not given it an instance name. I am trying to tell Flash that the following method is legal for the main timeline in the actions panel and send the timeline to frame 20


however when get to run it i get the following error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::[email protected] to flash.display.MovieClip.

I got this code snippet from a book called Learning Actionscript 3.0, pg 65. Can somebody tell me how i can get the movieclip to send the main timeline to frame 20 pls
