How Come my DataStore/Leaderboard won't work?

So I have a LeaderBoard that won't work and I don't get told why it won't work in the Developer Panel I don't exactly know why. What exactly could be going wrong?

---Script---

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

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.Value = DataStoreService:GetAsync(player.UserId) or 0
	
	local data
	local success, errormessage = pcall(function()
		data = myDataStore:GetAsync(player.UserId.."-cash")
	end)
	
	if success then
		cash.Value = data
	else
		print("There was a error whilst getting your data")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	
	local success, errormessage = pcall(function()
		myDataStore:SetAsync(player.UserId.."-cash",player.leaderstats.Cash.Value)
	end)
	
	if success then
		print("Player Data successfully saved!")
	else
		print("There was a error when saving data")
		warn(errormessage)
	end
	
end)

cash.Parent = leaderstats

For Flowery

local DataStoreService = game:GetService("DataStoreService")
	 
local myDataStore = DataStoreService:GetDataStore("myDataStore")
	 
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
	cash.Value = 0
	 
	local data
	local success, errormessage = pcall(function()
	    data = myDataStore:GetAsync(player.UserId.."-cash")
	end)
	 
	if success then
	    cash.Value = data
	else
	    print("There was a error whilst getting your data")
	    warn(errormessage)
	end
end)
	 
game.Players.PlayerRemoving:Connect(function(player)
	 
	local success, errormessage = pcall(function()
	    myDataStore:SetAsync(player.UserId.."-cash",player.leaderstats.Cash.Value)
	end)
	 
	if success then
	    print("Player Data successfully saved!")
	else
	    print("There was a error when saving data")
	    warn(errormessage)
	 end
	 
end)
