Datastore doesn't work? It doesn't save!?

So I tried to make a script that saved your points, however the points does not save. I don't get any errors, nor do I get any errors in the game when I press F9. Any soloutions! Thanks!

local DataStore = game:GetService("DataStoreService"):GetDataStore("Points")

game:GetService("Players").PlayerAdded:connect(function(Player)
    local leaderstats = Instance.new("IntValue", Player)
    leaderstats.Name = "leaderstats"
    local cash = Instance.new("IntValue", leaderstats)
    local x = Instance.new("IntValue", leaderstats)
    cash.Name = "Level"
    cash.Value = 0
    x.Name = "XP"
    x.Value = 0
    local key = "user-"..Player.userId
    local SavedPoints = DataStore:GetAsync(key)
    if SavedPoints ~= nil then  
        cash.Value = SavedPoints[1]
        x.Value = SavedPoints[2]
    else
        local ValuesToSave = {cash.Value, x.Value}
        DataStore:SetAsync(key, ValuesToSave)
    end
    x.Changed:connect(function()
        cash.Value = math.floor(x.Value / 50)
    end)
end)
game.Players.PlayerRemoving:connect(function(plr)
    local key = "user-"..plr.userId
    local ValuesToSave = {plr.leaderstats.cash.Value,plr.leaderstats.x.Value}
    DataStore:SetAsync(key, ValuesToSave)
end)
