help me with duplicating movie clips

[ymxbc]

I need help with creating multiple copies(3) of a movie clip. here's the actionscript i use to make one copy of it:

mc3.duplicateMovieClip("newclip"+3,level);

// set a random position
_root["newclip"+level]._x = int(Math.random()*550);
_root["newclip"+level]._y = int(Math.random()*400);

// increase level
level++;
}
