Lua If already monster then no summon next

[Fresh]

Hello.
I need an function to this script:

local left = {x=3068, y=3074, z=7, stackpos=2}
local right = {x=3070, y=3074, z=7, stackpos=2}
 
local summon = {x=3067, y=3072, z=7}
 
function onUse(cid, item, fromPosition, itemEx, toPosition)
	if item.itemid == 1945 then
		local a = getThingfromPos(left)
		if a.itemid == 11754 and a.type >= 2 then
			local b = getThingfromPos(right)
			if b.itemid == 11754 and b.type >= 2 then
				doRemoveItem(a.uid, 2)
				doRemoveItem(b.uid, 2)
				doCreateMonster('Wolf', summon)
				doSendMagicEffect(summon, 121)
				doCreatureSay(cid, 'You lost two wolfs skin and an Wolf appear.', 0x13)
				return doTransformItem(item.uid, 1946)
			end
		end
		return doPlayerSendCancel(cid,"Put the right items in the right spots!")
	end
	return doTransformItem(item.uid, 1945)
end

If an creature is in summon position than player cant use lever.
Anyone ?

add this

function onUse(cid, item, fromPosition, itemEx, toPosition)
      if isPlayer(cid) then
	if item.itemid == 1945 then
		local a = getThingfromPos(left)
		if a.itemid == 11754 and a.type >= 2 then
			local b = getThingfromPos(right)
			if b.itemid == 11754 and b.type >= 2 then
				doRemoveItem(a.uid, 2)
				doRemoveItem(b.uid, 2)
				doCreateMonster('Wolf', summon)
				doSendMagicEffect(summon, 121)
				doCreatureSay(cid, 'You lost two wolfs skin and an Wolf appear.', 0x13)
				return doTransformItem(item.uid, 1946)
			end
                     end
		end
		return doPlayerSendCancel(cid,"Put the right items in the right spots!")
	end
	return doTransformItem(item.uid, 1945)
end

if it's an area and not just a single position, use something like this

local left = {x=3068, y=3074, z=7, stackpos=2}
local right = {x=3070, y=3074, z=7, stackpos=2}

local summon = {x=3067, y=3072, z=7}

local from = {x=100, y=100, z=7} -- top left corner
local to = {x=200, y=200, z=7} -- bottom right corner

function onUse(cid, item, fromPosition, itemEx, toPosition)
	if item.itemid == 1945 then
		local a = getThingfromPos(left)
		if a.itemid == 11754 and a.type >= 2 then
			local b = getThingfromPos(right)
			if b.itemid == 11754 and b.type >= 2 then
				for x = from.x, to.x do
					for y = from.y, to.y do
						local f = getTopCreature({x=x, y=y, z=from.z}).uid
						if f ~= 0 and isMonster(f) and getCreatureMaster(f) == f and getCreatureName(f):lower() == 'wolf' then
							return doPlayerSendCancel(cid, 'The monster is already summoned.') 
						end
					end
				end
				doRemoveItem(a.uid, 2)
				doRemoveItem(b.uid, 2)
				doCreateMonster('Wolf', summon)
				doSendMagicEffect(summon, 121)
				doCreatureSay(cid, 'You lost two wolfs skin and an Wolf appear.', 0x13)
				return doTransformItem(item.uid, 1946)
			end
		end
		return doPlayerSendCancel(cid, 'Put the right items in the right spots!')
	end
	return doTransformItem(item.uid, 1945)
end
