How to load and save leaderboards data? None of the things are working, so i decided to ask here

--var local datastore = game:GetService("DataStoreService") local ds1 = datastore:GetDataStore("MoneyData") local ds2 = datastore:GetDataStore("LevelData") local ds3 = datastore:GetDataStore("RebirthData")

local cooldown = 60

--work game.Players.PlayerAdded:Connect(function(plr)

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

local money = Instance.new("IntValue")
money.Name = "Money"
money.Parent = leaderstats

local level = Instance.new("IntValue")
level.Name = "Level"
level.Parent = leaderstats

local rebirths = Instance.new("IntValue")
rebirths.Name = "Rebirths"
rebirths.Parent = leaderstats

local moneyData										-- money
local successMoney, errorMoney = pcall(function()
	moneyData = ds1:GetAsync(plr.UserId.." _money")
end)

local levelData										-- level
local successLevel, errorLevel = pcall(function()
	levelData = ds2:GetAsync(plr.UserId.." _level")
end)

local rebData										-- rebirths
local successReb, errorReb = pcall(function()
	rebData = ds3:GetAsync(plr.UserId.." _rebirths")
end)



if successMoney then
	money.Value = moneyData
else
	print("We couldnt store the money")
	warn(errorMoney)
end

if successLevel then
	level.Value = levelData
else
	print("We couldnt store the level")
	warn(errorLevel)
end

if successReb then
	rebirths.Value = rebData
else
	print("We couldnt store the reborths")
	warn(errorReb)
end


while wait(cooldown) do
	ds1:SetAsync(plr.UserId.." _money", money.Value)
	ds2:SetAsync(plr.UserId.." _level", level.Value)
	ds3:SetAsync(plr.UserId.." _rebirths", rebirths.Value)
	print("Data autosaved")
end

end)

game.Players.PlayerRemoving:Connect(function(plr)

local successMoney, errorMoney = pcall(function()
	ds1:SetAsync(plr.UserId.." _money", plr.leaderstats.Money.Value)
end)	

local successLevel, errorLevel = pcall(function()
	ds2:SetAsync(plr.UserId.." _level", plr.leaderstats.Level.Value)
end)
	
local successReb, errorReb = pcall(function()
	ds3:SetAsync(plr.UserId.." _rebirths", plr.leaderstats.Rebirths.Value)
end)
	

if successMoney then
	print("money data stored successfully")
else
	print("We couldnt store the money")
	warn(errorMoney)
end

if successLevel then
	print("level data stored successfully")
else
	print("We couldnt store the level")
	warn(errorLevel)
end

if successReb then
	print("rebirths data stored successfully")
else
	print("We couldnt store the rebirths")
	warn(errorReb)
end

end)
