My developer product handler doesnt give the player any bucks when the product is bought?

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

local function processReceipt(receiptInfo)
	local player = players:GetPlayerByUserId(receiptInfo.PlayerId)
	local productId = receiptInfo.ProductId
	if not player then
		
		return Enum.ProductPurchaseDecision.NotProcessedYet
	end
	
	if productId == 970585872 then
		local FindPlayer = game.Players:FindFirstChild(player.Name)
		local Bucks = player.leaderstats.Bucks
		if Bucks then
			Bucks.Value = Bucks.Value + 100
		end
	elseif productId == 970585931 then
		local FindPlayer = game.Players:FindFirstChild(player.Name)
		local Bucks = player.leaderstats.Bucks
		if Bucks then
			Bucks.Value = Bucks.Value + 500
		end
	elseif productId == 970585980 then
			local FindPlayer = game.Players:FindFirstChild(player.Name)
			local Bucks = player.leaderstats.Bucks
			if Bucks then
				Bucks.Value = Bucks.Value + 1000	
			end
	elseif productId == 970585980 then
				local FindPlayer = game.Players:FindFirstChild(player.Name)
				local Bucks = player.leaderstats.Bucks
				if Bucks then
					Bucks.Value = Bucks.Value + 1000	
			end
	elseif productId == 970586164 then
				local FindPlayer = game.Players:FindFirstChild(player.Name)
				local Bucks = player.leaderstats.Bucks
				if Bucks then
					Bucks.Value = Bucks.Value + 2500	
			end
	elseif productId == 970586212 then
				local FindPlayer = game.Players:FindFirstChild(player.Name)
				local Bucks = player.leaderstats.Bucks
				if Bucks then
					Bucks.Value = Bucks.Value + 5000	
			end
		
		return Enum.ProductPurchaseDecision.PurchaseGranted
		
	end
	
end

MarketplaceService.ProcessReceipt = processReceipt
