help me with duplicating movie clips

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++;
}

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

Not sure it matters. but aren't you nameing them all the same?
try
mc3.duplicateMovieClip("newclip"+level.toString(), level);

Also instead of level at the end you can use

getNextHighestDepth()

i got it now

Thanks a lot
