Flash 8 - actionscript button problem

Question

Hi all,
I created a button "place holder" (until I had time to design
my own) on an object using the standard button component, this
worked great. When I replaced it with my own user defined button it
stopped working. The object has the same name and is referenced
identically.
Can anyone explain this weird behaviour?
Here is my code (worked for standard button but not for user
defined)
var invMenuState:Number = 0;
// function for the Next button
function inventorySlider(eventObj:Object) {
switch(invMenuState) {
case 0:
inventory_mc.gotoAndPlay("slideUp");
invMenuState = 1;
break;
case 1:
inventory_mc.gotoAndPlay("slideDown");
invMenuState = 0;
// add the event listener for the button
inventory_mc["inventory_bx"]["inventory_btn"].addEventListener("click",
inventorySlider);
thanks,
Paul.

i think you're confused between the button component and the
button class - not that hard to do really, thinking about it.
as kglad mentioned, button symbols require handlers from the
button class such as onPress which is the equivalent to the line of
code you were using with your button component.
