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)
