tutorial problem

hi,

i am doing this pop up menu tutorial.

http://www.flashkit.com/tutorials/Ac...-121/more5.php

i am having some problems though. it says to put that action in, but it isn't working. when i double click on the button, i go to the area where it has hit | over | down etc. because its a button, and you can't add an action script. ?? help please. thanks

Codes for buttons are applied ON the button , not inside.
