usermessage problem

[MaZy]

EDIT: OH sorry, I missclicked to wrong section. It should be "Developer Discussion" :S

Hello
I try to make an addon for TTT Gamemode (serverside).

Problem is wiki says usermessage.Hook is shared. So I thought perfect. So I tried this function and it doesn't work. I don't receive anything :(

if GAMEMODE.Name == "Trouble in Terrorist Town" then
	print("[ET]: Gamemode", GAMEMODE.Name)

	local function CustomReceiveGameMsg(um)
	   local text = um:ReadString()
	   local special = um:ReadBool()

	   print(text)
	end
	usermessage.Hook("game_msg", CustomReceiveGameMsg)
end

A other idea?

EDIT2: Problem solve.. had to make other way
