data dosen't save even when I did a loop and used findfirstchild?

So basically the inventory is a folder with weopons inside it and the weopons all have a IntValue inside them called IDNumber each of them have a value the variable nok is the IntValue it won't save for some reason

local DataStore = game:GetService("DataStoreService"):GetDataStore('ToolSave')
game.Players.PlayerAdded:Connect(function(plr)
	local savedStuff = DataStore:GetAsync(plr.userId)
	if savedStuff ~= nil then
		for i,v in pairs(savedStuff) do
			for a,k in pairs(game.ServerStorage.Inventory) do
				IDnumebr = k:FindFirstChild('IDNumber')
				if v == IDnumebr.Value then
					print(k.Name)
				local weopon = IDnumebr.Parent:Clone()
				weopon.Parent = plr:WaitForChild('Backpack')
				
					
				end
			end
			
		end
	end
plr.CharacterRemoving:Connect(function()
	plr.Character.Humanoid:UnequipTools()
	
end)
end)



game.Players.PlayerRemoving:Connect(function(plr)
	Table = {}
	for i,v in pairs(plr.Backpack:GetChildren()) do
		table.insert(Table,v:WaitForChild('IDNumber').Value)
	end
if Table ~= nil then
	DataStore:SetAsync(plr.userId,Table)
end
end)
