DuplicateMov

[Jjp_productions]

When duplicating a movie clip, I can only seem to duplicate one. Here’s my script. What I mean is, I click it, and it duplicates. I click it again and it wont anymore.

 
onClipEvent (load) {
 i = 1;
}
on (press) {
 i+=1;
 this.duplicateMovieClip("circle"+i, i, {_x:_root.spawn._x, _y:_root.spawn._y, _alpha:100});
 _root.spawn._y += 50;
}
