Trying to load a MC

1

I need to load a MC from the libaray to the stage during the currnet condition.

if(_root.tracer == 10){
_root.alert = “Hello”
_root.attachMovie(“Score”, “score”, 10);
_root.score.play();
}

I know the condition works because “alert” is a dynamic text field and shows hello on the screen.

the movieclip “Score” is in the libaray and linked for action script.
But wont show up.
