Leaderstats not working

Help and Feedback Scripting Support
#1

I made this leaderstats script which saves values in two folder. I addad a third folder called lines but when I print the data the data for the lines is nil, but for the money it works fine.

local DataStoreService = game:GetService("DataStoreService")
local myDataStore = DataStoreService:GetDataStore("myDataStore2")
local players = game:GetService("Players")

local mainModule = require(game.ReplicatedStorage.Modules.MainModule)

players.PlayerAdded:Connect(function(player)
	local leaderstatsTable = {
		["Money"] = 0,
	}

	local valuesTable = {
		["Bruh"] = 0,
	}
	
	local linesTable = {}
	
	for i,v in mainModule.Lines do
		if i == 1 then
			linesTable[i] = 0
		else
			linesTable[i] = -1
		end
	end

	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local valuesFolder = Instance.new("Folder")
	valuesFolder.Name = "Values"
	valuesFolder.Parent = player
	
	local linesFolder = Instance.new("Folder")
	linesFolder.Name = "Lines"
	linesFolder.Parent = player

	local data
	local success, err = pcall(function()
		data = myDataStore:GetAsync(player.UserId)
	end)

	for name, value in pairs(leaderstatsTable) do
		local newValue = Instance.new("IntValue")
		newValue.Name = name
		newValue.Value = value
		newValue.Parent = leaderstats

		if success and data and data[name] then
			newValue.Value = data[name]
		end
	end

	for name, value in pairs(valuesTable) do
		local newValue = Instance.new("IntValue")
		newValue.Name = name
		newValue.Value = value
		newValue.Parent = valuesFolder

		if success and data and data[name] then
			newValue.Value = data[name]
		end
	end
	
	for name, value in pairs(linesTable) do
		local newValue = Instance.new("IntValue")
		newValue.Name = name
		newValue.Value = value
		newValue.Parent = linesFolder
		
		if success and data and data[name] then
			newValue.Value = data[name]
		end
	end
end)

function tableTheTable(theTable)
	local tbl = {}

	for _, intValue in pairs(theTable:GetChildren()) do
		tbl[intValue.Name] = intValue.Value
	end

	return tbl
end

local function dataToTable(data1,data2)
	local data = {}

	for i,v in pairs(data1) do
		data[i] = v
	end

	for i,v in pairs(data2) do
		data[i] = v
	end

	return data
end

players.PlayerRemoving:Connect(function(player)
	local leaderstatsFolder = player:FindFirstChild("leaderstats")
	local valuesFolder = player:FindFirstChild("Values")
	local linesFolder = player:FindFirstChild("Lines")
	
	if valuesFolder and leaderstatsFolder then
		local dataToSave = dataToTable(tableTheTable(leaderstatsFolder),tableTheTable(valuesFolder),tableTheTable(linesFolder))

		local success, err
		local attempt = 1

		repeat
			success, err = pcall(function()
				myDataStore:SetAsync(player.UserId, dataToSave)
			end)

			attempt += 1
			task.wait(2)
		until success or attempt > 4

		if success then
			print(player.Name .. "'s data was success fully saved")
		else
			print(player.Name .. "'s data failed to save")
		end
	end
end)

This should fix the problem with your Lines folder data not being saved and retrieved correctly.
