Hierarchy in ActionScript?

Sup All

Alrighty, still fairly new to the flash scene, but slowly I’m figuring things out.
Okay my navigation menu is made up of a few movie clips that open up to dropdown menu buttons. Anyway I can’t figure out where to place the coding, or if there is a hierarchy in the script.

For example the first item in the menu :: you rollOver onto it and it displays the rest of the hidden menu ::

attached to the button in actionscript is ::

on (rollOver)
{
gotoAndStop(“open”);
}

But I also want to add

on (release)
{
_root.contents.loadMovie(“student.swf”);
}

Can I have both of these actions attached to the same button? Or am I totally lost and I should put the loadMovie action some place else. Attached is the .fla file :: If you have time to gander at it that would be great, or if you can solve my problem w/o it Thank you so much

Thank you in advance
