Did I put the PurchaseGranted - line in the correct place in this script?

I am generally new to developer products, that is why I wnat to know if I put the PurchaseGranted - line in the correct place.

local plr = script.Parent.Parent.Parent.Parent.Parent
local link = game:GetService("MarketplaceService")
deb = 0
script.Parent.MouseButton1Click:connect(function()
    local marketId = 43143148  --ID OF YOUR DEVELOPER PRODUCT  
    link:PromptProductPurchase(plr,marketId)
    link.ProcessReceipt = function(receiptInfo)
        if Enum.ProductPurchaseDecision.PurchaseGranted and receiptInfo.PlayerId == plr.userId then
            if deb == 0 then
                deb = 1
                plr.leaderstats.Snowflakes.Value = plr.leaderstats.Snowflakes.Value + 5000 --Alter what stat you would like to increase or decrease after the player has purchased.
                wait(1)
                deb = 0
            end
            return Enum.ProductPurchaseDecision.PurchaseGranted
        end
    end
end)
