global variables on server/npc?

[spider661]

is there a way to set a variable on an npc or the server that other npcs can read?

i have a quest and players turn in an item and get ported to an area with a boss.. i need that boss to see how many players actually have the quest and how many don't then drop a amount of items so that all that have the quest get the items and all that don't. don't get the item so basically items drop ass needed and not jsut a set amount of 6 per say. sense it is a raid boss there could only be 1 player needing the item then there could be 20 players needing it.
