How to transition out

Hi All

I found the tutorial here on how to make page transitions. I understand how to make my content do neat things coming IN to the screen but how do I make it do neat things on its way out? I can’t seem to find the code for this but I think it must be pretty simple.

This is the code I’ve got on each button at the moment -

on (rollOver) {
_root.mouse_over_contact_mc = true;
}

on (rollOut) {
_root.mouse_over_contact_mc = fstartlse;
}

on (release){
sections.gotoAndPlay(“contact”);
}

Here is the link to what I’ve got thus far minus any page transitions http://preview.roanoke.com/proof/partymachine2.html Any help is much appreciated! Thanks
