local castle_status = status:getDataInt("status")
						
   if isPlayer(cid) == TRUE and isPlayer(target) == TRUE then
	local player_1_gid = getPlayerGuildId(cid)
	local player_2_gid = getPlayerGuildId(target)
	   if player_1_gid == team_1_id and player_2_gid == team_2_id and castle_status == 1 then
		team2_count = team_2_id - 1
	   end
