Trying to Figure out Error 1119

I am trying to figure out how to tell if my FLV is done playing or not.  I have imported it in (its on a flash streaming server) so I did FILE -> IMPORT MOVIE.  It works great but I was trying to add this code and this seems to be where my problem is. Has anyone had this problem before and know why or how to fix it? Thanks.

CODE:

arrival_M.addEventListener(VideoEvent.COMPLETE, completePlay);

function completePlay ():void

{

          trace("Movie Done");

}
