Duplicating my movieclip to an area

I have a game where you click a button and I want a movieclip to be duplicated in a certain area which is a movie clip named swamp_mc.

On the button I am writing:

on (press) {
	i = i + 1;
	duplicateMovieClip (_root.medowCar_mc, "medow" + i, i);
}

But on the actual movieclip at the moment it just randomizes the location like so and only allows one to be duplicated where I want every time it clicks the it produces another copy of the movieclip:

onClipEvent (load) {
	this._x = random(822);
	this._y = random(147);
}

Please help :frowning:
