I dont see much wrong with the menu build or anything its self
Have you tried editing the zone = if so you might have made a little error in there
Have you executed your rawfile from the buttons_default.cfg etc

Tell me if you've done that and if you havn't rename
maps/mp/_events.gsc to buttons_default.cfg & maps/mp/_utility.gsc to buttons_tactical.cfg and execute the rawfile where your menu is

Hope this works and helps
