actionscript 3 - Flash Game objects won't go away -

i have flash movie interactive game in middle. game simple drag , drop target.

now problem: when user plays game drag , drop symbols stays in target spot on next frame end of movie.

i them disappear after game over. noobie actionscript 3.0 - code can implement on frames after game make sure objects wont showup.

thanks..

frame navigation not affect objects created code (or objects created frames modified code). need manually remove them via removechild().
