Problem with timer

[jdmmer]

I have a problem with my timer, it keeps saying: UTIL_GetListenServerHost() called from a dedicated server or single-player game.

Can someone help me with fixing this piece of code?

function PLUGIN.builderTime(player, team)
timer.Create("buildtimer", 5, 0, function()
		if(player:Team() == TEAM_BUILDER) then
			cider.team.make(player, TEAM_CITIZEN);
		end
	end)
end

-- Add the hook
hook.Add("Think", "builderTime", PLUGIN.builderTime)

Thanks
