My datastore script is not saving any data and it is giving this error: ServerScriptService.Leaderstats:22: attempt to index nil with number

Here is my script:

local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("SaveData")

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Parent = leaderstats
	
	local exp = Instance.new("IntValue")
	exp.Name = "Exp"
	exp.Parent = leaderstats
	
	local data
	local success, errorMessage = pcall(function()
		data = dataStore:GetAsync(player.UserId)
	end)
	if success then
		cash.Value = data[0]
		exp.Value = data[1]
	else
		print("Player has no data")
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local dataToSave = {
		player.leaderstats.Cash.Value,
		player.leaderstats.Exp.Value
	}
	local success, errorMessage = pcall(function()
		dataStore:SetAsync(player.UserId, dataToSave)
	end)
	if success then
		print("Data saved")
	else
		print("Data not saved")
		warn(errorMessage)
	end
end)

My EXP saves now but my money doesn’t.

Ok it all works now, I just named the data[index] stuff wrong.
