I want to help but currently its impossible since i dont know how your crafting script works. I would appreciate it if you would copy and paste the script so i can take a look and maybe help solve the issue (:

Ok here an example
Item = Backpack[wood]
Item2 = Backpack[wood]
On mouse click ()
Item:remove ()
Item2:remove()
Here a problem when the items remove all wood that in backpack are gone I want it to delete only 2 wood from my backpack sorry for my english

Well… i still dont know exaclly how your script looks
I decided to create this module script which should hopefully solve your issue, Its not perfect but it gets the job done.

How to use this module script:

local CraftModule = require(Path.To.CraftModule) -- put the actual path to your module

local recepie = {
	["Wood"] = 2,
	["Iron"] = 1
	-- you can add any items you want
}

CraftModule.Craft(yourPlayer, recepie, someRewardItem) -- handles everything

CraftModule:
(I would recommend putting your module script somewhere in ServerScriptService)

local CraftModule = {}

function CraftModule.Craft(player, recepie, craftResult) -- Reruns true if the craft was successfull
	local itemDictionary = FindItems(player, recepie)
	if CanCraft(itemDictionary, recepie) then
		RemoveItems(itemDictionary) -- destroy all of the necessary items
		local resultItem = craftResult:Clone() -- clone and add the craftResult to the player backpack
		resultItem.Parent = player.Backpack
		print("Successfully crafted!")
		return true
	else
		print("Not enought items to craft!")
		return false
	end
end

function FindItems(player, recepie) -- Retuns all the items that were in the player backpack matching the recepie
	local itemDictionary = {}
	for i, item in ipairs(player.Backpack:GetChildren()) do -- loop over the backpack
		local amount = recepie[item.Name]
		if item:IsA("Tool") and amount then -- if the recepie contains the item name
			itemDictionary[item.Name] = itemDictionary[item.Name] or {} -- if itemDictionary[item.Name] is nill then create a new table for it
			if #itemDictionary[item.Name] < amount then -- if the amount of found items with this name is smaller than the needed amount then... 
				table.insert(itemDictionary[item.Name], item) -- add this item to the table
			end
		end
	end
	
	return itemDictionary
end

function CanCraft(itemDictionary, recepie) -- Returns true if there are enought items for the craft to happen
	for name, amount in pairs(recepie) do -- loop over the recepie
		if not itemDictionary[name] or #itemDictionary[name] < amount then -- if there are not enought items with this name then return false
			return false
		end
	end
	
	return true -- if all of the items match then return true
end

function RemoveItems(itemDictionary) -- Destroys all of the given items
	for k, items in pairs(itemDictionary) do
		for i, item in ipairs(items) do
			item:Destroy()
		end
	end
end

return CraftModule

Of course you can change this module script however you want but this can be a good starting point. I hope this helps!
