Lua (0.4) Mortal combat arena [ZAO]

[marek12]

Hey guys, I am looking for working mortal combat arena on zao.
At the moment my script looks like this

local from = {x=33052, y=30989, z=3}
local to = {x=33067, y=31004, z=3}

local monsters = {
{{x=33064, y=30996, z=3}, "Baron Brute"},
{{x=33064, y=30997, z=3}, "The Axeorcist"}
}

local players = {
{{x=33076, y=30977, z=2}, {x=33051, y=30997, z=3}},
{{x=33077, y=30977, z=2}, {x=33051, y=30998, z=3}}
}

local level = 120

function onUse(cid, item, fromPosition, itemEx, toPosition)
local t = {}
if item.itemid == 1945 then
for i = 1, #players do
t[i] = getTopCreature(players[i][1]).uid
if not isPlayer(t[i]) then
return doCreatureSay(cid, 'You need ' .. #players .. ' players to do this quest.', TALKTYPE_ORANGE_1, false, cid)
elseif getPlayerLevel(cid) < level then
return doCreatureSay(cid, 'All players have to be level ' .. level .. ' to do this quest.', TALKTYPE_ORANGE_1, false, cid)
end
end
for i = 1, #t do
doTeleportThing(t[i], players[i][2])
doSendMagicEffect(players[i][1], CONST_ME_TELEPORT)
doSendMagicEffect(players[i][2], CONST_ME_TELEPORT)
end
for i = 1, #monsters do
doCreateMonster(monsters[i][2], monsters[i][1])
doSendMagicEffect(monsters[i][1], CONST_ME_TELEPORT)
end
else
for x = from.x, to.x do
for y = from.y, to.y do
local v = getTopCreature({x=x, y=y, z=from.z}).uid
if isPlayer(v) then
return doCreatureSay(cid, 'There is already a team in the battle room.', TALKTYPE_ORANGE_1, false, cid)
elseif isMonster(v) then
table.insert(t, v)
end
end
end
for i = 1, #t do
doRemoveCreature(t[i])
end
end

return doTransformItem(item.uid, item.itemid == 1945 and 1946 or 1945)
end

and the problem is, when people enters arena, there are first 2 bosses spawned, after killing them summons spawning, but after killing them, nothing happens(next monsters are not spawning). Also no errors in console.
don't really know if it's problem with this script or the problem isn't in action script.
If anyone got working script, can you pelase share?
