Datastore Is Not Saving Player Data No Error?

I am just beginning to learn about datastores but the one I modified below does not save the player's money. I do not get any errors in the output. What is the error?

local MoneyBindableEvent = game:GetService("ReplicatedStorage").Events:WaitForChild("AddMoney")



local array = {}



game.Players.PlayerAdded:Connect(function(player)

local leaderstats = Instance.new("Folder", player)

leaderstats.Name = "leaderstats"

local points = Instance.new("IntValue", leaderstats)

points.Name = "Money"

points.Value = game:GetService("DataStoreService"):GetDataStore("Money"):GetAsync("user_" ..player.userId)

array[player.Name] = points.Value



end)





MoneyBindableEvent.Event:Connect(function(price, plr)

print("Recieved")

local player = game.Players:WaitForChild(plr)

player.leaderstats.Money.Value = player.leaderstats.Money.Value + price

print("Price is $"..price)

print("Player is:"..plr)

end)



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

if array[player.Name] ~= nil then

game:GetService("DataStoreService"):GetDataStore("Money"):UpdateAsync("user_"..player.userId, function(oldValue)

local newValue = array[player.Name]

local val = newValue

return newValue

end)

wait()

array[player.Name] = nil

end

end)
