AS2:: Multiple hitTests

I am making a game where one object needs to hit test many so I have been trying to build it like so:

function HitTester() {
	trace("calling function");
	for (i=0; i<12; i++) {
		temp_A = eval(_global.CometArray);
		if (bottomHit_mc.hitTest(temp_A)) {


and to active it:

bottomHit_mc.onEnterFrame = function() {

But this doesn’t seem to work and as the enterFrame calls in the function so many times it is really slowing everything down.

Can anyone tell me where I am going wrong or a better way of doing it?
