Sparring problems

[wild8900]

I currently know how to make the area a sparring zone and disable and enable weapons when in or out of the sparring ring. The problem im having is I cant get the door of the spar ring to close on the servers side when 2 people are in the ring and 1 says start. Also, How do people make the D weapon disabled? Dont you use a blank npc? I also cant get the bomb to show im in the server's side too. this client and server side crap is so annoying
