Duplication Help

I was just playing around with the duplicate movie command and I ran into a problem. It deletes some of my earlier instances when I press the button. I have attached the fla. I think it has something to do with the level I load it on but i am not sure. Any help appreciated. Thanks.

change all of the i’s to _root.i

ahh. duh

One more question, how come my if statement isnt working? Additionally, it almost crashes my computer after about 5 clicks yet the duplicate movie tutorial can have literally hundreds before it even slows me down. why?
