Only one of my Dev Products works

Hello. I have four dev products for my game, but only one of them works for some reason.

Here is one of my scirpts, but I have 3 more that just have different ID’s and stuff but they do not work.
Why is this happening?

local DataStoreService = game:GetService("DataStoreService")
local LeaderstatDataStore = DataStoreService:GetDataStore("LeaderstatDataStore")

local DeveloperProductID = 1597899398 -- Change this ID with your Developer Product ID

	local Leaderstat = player.leaderstats.FairyDust

	local LeaderstatKey = player.UserId .. "FairyDust"
	local success, savedValue = pcall(function()
		return LeaderstatDataStore:GetAsync(LeaderstatKey)
	if success and savedValue then
		Leaderstat.Value = savedValue

	local Purchased = false

	game:GetService("MarketplaceService").ProcessReceipt = function(receiptInfo)
		if receiptInfo.PlayerId == player.UserId and receiptInfo.ProductId == DeveloperProductID and not Purchased then
			Purchased = true

			Leaderstat.Value = Leaderstat.Value + 250

			local Success, error = pcall(function()
				LeaderstatDataStore:SetAsync(LeaderstatKey, Leaderstat.Value)
			if not Success then
				warn("Failed to save leaderstat data:", error)
			Purchased = false
		return Enum.ProductPurchaseDecision.PurchaseGranted

Please help

I don’t see anywhere where you accomodate 3 other ids.

Well first of all you are defining the ProcessReceipt callback every time a player joins. Define it only once.

Try something like this instead (this is from a roblox tutorial)

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local productFunctions = {}

-- ProductId 123123 brings the user back to full health
productFunctions[123123] = function(receipt, player)
	if player.Character and player.Character:FindFirstChild("Humanoid") then
	player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
		-- Indicate a successful purchase
		return true

-- ProductId 456456 awards 100 gold to the user
productFunctions[456456] = function(receipt, player)
	local stats = player:FindFirstChild("leaderstats")
	local gold = stats and stats:FindFirstChild("Gold")

	if gold then
		gold.Value = gold.Value + 100
		return true

local function processReceipt(receiptInfo)
	local userId = receiptInfo.PlayerId
	local productId = receiptInfo.ProductId

	local player = Players:GetPlayerByUserId(userId)
	if player then
		-- Get the handler function associated with the developer product ID and attempt to run it
		local handler = productFunctions[productId]
		local success, result = pcall(handler, receiptInfo, player)
		if success then
			-- The user has received their benefits!
			-- return PurchaseGranted to confirm the transaction.
			return Enum.ProductPurchaseDecision.PurchaseGranted
			warn("Failed to process receipt:", receiptInfo, result)

	-- the user's benefits couldn't be awarded.
	-- return NotProcessedYet to try again next time the user joins.
	return Enum.ProductPurchaseDecision.NotProcessedYet

-- Set the callback; this can only be done once by one script on the server!
MarketplaceService.ProcessReceipt = processReceipt
