Data store isn't saving data?

If this doesn't work just comment and we can further debug.

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

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

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

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

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

    if success and data then
        cash.Value = data
    else
        warn(errormessage)
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local success, errormessage = pcall(function()
        local PlayerData = player.leaderstats.Money.Value
        local Key = player.UserId
        myDataStore:SetAsync(Key, PlayerData)
    end)

    if success == true then
        print("Data successfully saved!")
    else
        print("Data wasn't saved")
        warn(errormessage)
    end

end)

game.BindToClose:Connect(function()
    -- Gives enough time to save data
    -- Makes studio wait 5 seconds before closing the game/server
    -- You can remove this if you want, just for studio testing purposes
    wait(5)
    print("Bind: All data should be saved")
end)

Changes:

    Added "=" to pcalls so you can see if it threw an error
    Set variable "PlayerData" to the players money value-
		you had it set to nothing so the server was saving blank
    Checked if the server got some data and not just success
