Really REALLY simple question

Hi guys, this seems like such a simple question, but I can’t seem to crack it… I’m trying to use a loop with the CreateEmptyMovieClip method to make several different movie clips, but it seems that each time I make a new empty clip, it replaces the old one!

var counter:Number = 0;
function image(count) {
this.createEmptyMovieClip(counter, this_mc.getNextHighestDepth());
}
test_btn.onRelease = function() {
image(counter);
counter++;
};

For example, in the example, you press the test_btn once, you get a movie clip called ‘0’. You press it again, that move clip is replaced by one called ‘1’. What I want is, on the second click to have TWO movie clips, 1 and 2…

thanks,
