Developer Products Not Working?

I made a couple dev products in my game, and they dont seem to be working. i was thinking maybe it could be because of fe, but now i dont think it is.

Local Script:

local MarketplaceService = game:GetService("MarketplaceService")
local buyButton = script.Parent
local productId = 104671260
player = game.Players.LocalPlayer 
buyButton.MouseButton1Click:connect(function()
	MarketplaceService:PromptProductPurchase(player, productId)
end)

Server Script:

local MarketplaceService = game:GetService("MarketplaceService")
local productId = 104751949

MarketplaceService.ProcessReceipt = function(receiptInfo)
for i, player in ipairs(game.Players:GetChildren()) do
	if player.userid == receiptInfo.PlayerId then
    if receiptInfo.ProductId == productId then
	player.leaderstats.Money.Value = player.leaderstats.Money.Value+1000
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end
end
end
end

The developer product pops up and all and allows you to press buy and spend robux, but the Money value stays the same. Do i have to add that part to a totally new server script and fire it through the current server script? I am confused :P
