Problem with button

I was provided this fla by a user of this board, and i have no problem getting the rollover effect on it to work (button rolls out slower than it rolls in).

However, even though this brings up the mouseover symbol… i cannot add mouse effects to the buttons, making them useless (cannot add . But im guessing theres either a way around this, or im stupid and have done something wrong.

If i add the

on (release) {

code in expert mode, the rollover effect then stops working :h:

any ideas?
