Custom function w/ variables not working - help?

I’m using Flash MX 2004.


// function to automate the hit tests
function hitClip (aCPlaceNum, loopNum, loopName, aCButtonNum) {
	aCPlaceNum.gotoAndStop(5);
	loopNum.attachSound(loopName);
	loopName.gotoAndStop(5);
	aCButtonNum = loopName;
}

ambPho.onRelease = function () {
	if ( ambPho.hitTest(aCPlace01) == true ) {
		hitClip ("aCPlace01", "loop01", "ambientPhotek", "aCButton01");
	}
}

Can you please tell me why this isn’t working? It takes me 10 minutes to test the movie every time and it’s taking me forever to fix things.

Do I have to do something else with the variable names I’m using or something?

Thanks for your help.
