leaderboard not saving data?

I made a leaderboard that is supposed to save the player's data but this error keeps popping out and yes I checked the little box to enable API Services.

Output Error: "ServerScriptService.Leaderboard:17: attempt to index global 'data' (a nil value)"

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

game.Players.PlayerAdded:Connect(function(player)
	local leaderboard = Instance.new("Folder",player)
	leaderboard.Name = "Leaderboard"

	local cash = Instance.new("IntValue",leaderboard)
	cash.Name = "Cash"
	cash.Value = 10
	
	local recieved,failed = pcall(function()
		local data = dataStore:GetAsync("User-"..player.UserId)
	end)
	
	if recieved then
		cash.Value = data[1]
		print("Data was received")
	else
		print("Data was not received")	
	end
	
	while true do wait(30)
		dataStore:GetAsync("User-"..player.UserId{cash.Value})
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local leaderboard = player.Leaderboard
	local cash = leaderboard.Cash
	
	local saved,failed = pcall(function()
		dataStore:SetAsync("User-"..player.UserId{cash.Value})
	end)
	
	if saved then
		print("Data was saved")
	else
		print("Data was not saved")
	end
end)

Some assistance would be helpful if anyone knows how to fix this kind of problems.

Oh I see how it's not working, Line 24 should be "SetAsync" not "GetAsync"
