Saving data and reloading it using Data Stores when I rejoin does not work, why?

Here are the 2 pieces of code:

local dsservice = game:GetService("DataStoreService"):GetDataStore("atcunleashed898")
game.Players.PlayerAdded:Connect(function(plr)
	local uniquekey = "id-"..plr.UserId
	local money = game.ReplicatedStorage:WaitForChild("getmoney"):InvokeClient(plr)
	local getsaved = dsservice:GetAsync(uniquekey)
	print(money)
	local numbersforsaving = {money}
	dsservice:SetAsync(uniquekey,money,numbersforsaving)
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local moneyvalue = game.ReplicatedStorage.getmoney:InvokeClient(plr)
	print(moneyvalue)
	local uniquekey = "id-"..plr.UserId
	local savetable = {moneyvalue}
	dsservice:SetAsync(uniquekey,moneyvalue,savetable)
end)

function getMoney()
	script.Parent:WaitForChild("backdrop"):WaitForChild("money")
	return script.Parent.backdrop.money.Value
end

game.ReplicatedStorage.getmoney.OnClientInvoke = getMoney

Make sure the 2nd script is in a localscript. Also, SetAsync only takes 2 arguments (the unique key and the value stored) and you have provided 3. Also, I don't think the server to client communication is needed unless the value is under PlayerGui. Also, you are never setting the value of the money from the DataStore in your script.
