Why is the DataStore not working?

So I made a DataStore script in and it did not work. Any fixes?

Faulty script 1:

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


game.Players.PlayerAdded:connect(function(player)
	
	local stats = Instance.new("IntValue", player)
	stats.Name = "leaderstats"
	
	local cash = Instance.new("IntValue", stats)
	cash.Name = "Money"
	cash.Value = cash.Value + 100
	
	local key = "player-"..player.userId
	
	local savedValues = DataStore:GetAsync(key)
	
	if savedValues then
		--Save format: {cash, coins}
		cash.Value = savedValues
	else
		local valuesToSave = {cash.Value}
		DataStore:SetAsync(key, valuesToSave)
	end
	
end)

Faulty code 2:

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

game.Players.PlayerRemoving:connect(function(player)
	
	local key = "player-"..player.userId
	
	--Save key: {cash}
	local valuesToSave = {player.leaderstats.Money.Value}
	DataStore:SetAsync(key, valuesToSave)
	
end)
