Save IntValues on Player?

So far I have been able to save data on leaderstats. Next what I want to do is save the value of how much it costs to rebirth. I cant seem to find anything online about it except how to save the leaderstats which I already did.

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

local function onPlayerJoin(player)
	
	local leaderstats = Instance.new("Folder") -- Don't Change
	leaderstats.Name = "leaderstats" -- Don't Change
	leaderstats.Parent = player -- Don't Change

	local Potatoes = Instance.new("IntValue")
	Potatoes.Name = "Potatoes"
	Potatoes.Parent = leaderstats
	
	local Rebirths = Instance.new("IntValue")
	Rebirths.Name = "Rebirths"
	Rebirths.Parent = leaderstats
	
	local GoldenPotatoes = Instance.new("IntValue")
	GoldenPotatoes.Name = "GoldenPotatoes"
	GoldenPotatoes.Parent = leaderstats
	
	local Music = Instance.new("BoolValue")
	Music.Name = "Music"
	Music.Parent = player
	Music = true
	
	local OneRebirthInt = Instance.new("IntValue")
	OneRebirthInt.Name = "OneRebirthInt"
	OneRebirthInt.Parent = player
	
	
	local playerUserId = 'Player_' .. player.UserId 
	local data = ds:GetAsync(playerUserId)
	if data then
		Potatoes.Value = data['Potatoes']
		Rebirths.Value = data['Rebirths']
	else
		Potatoes.Value = 0
		Rebirths.Value = 0
	end
	
end

local function create_table(player)
	local player_stats = {}
	for _, stat in pairs(player.leaderstats:GetChildren()) do
		player_stats[stat.Name] = stat.Value
	end
	return player_stats
end

local function onPlayerExit(player)
	local player_stats = create_table(player)
	local success, err = pcall(function()
		local playerUserId = 'Player_' .. player.UserId
		ds:SetAsync(playerUserId, player_stats)
		
	end)
	
	if not success then
		warn('Could not save data')
	end
	
end

game.Players.PlayerAdded:Connect(onPlayerJoin)
game.Players.PlayerRemoving:Connect(onPlayerExit)
