How to I make the save money data work?

So, I got the script from toolbox and I edited it a little bit. I tested it out, but it didn't work.

Here's the script:

local DSService = game:GetService('DataStoreService'):GetDataStore("DataStore")
game.Players.PlayerAdded:connect(function(plr)
	-- Define variables
	local uniquekey = 'id-'..plr.userId
	
	-- GetAsync
	local GetSaved = DSService:GetAsync(uniquekey)
	if GetSaved then
		game.Players.leaderstats.Money.Value = GetSaved[1]
	else
		local NumbersForSaving = {game.Players.leaderstats.Money.Value}
		DSService:SetAsync(uniquekey, NumbersForSaving)
	end
end)

game.Players.PlayerRemoving:connect(function(plr)
local uniquekey = 'id-'..plr.userId
local Savetable = {plr.leaderstats.Cash.Value}
DSService:SetAsync(uniquekey, Savetable)	
	
	
end)
