Why is this not giving me the tool when I purchase it?

It worked once then I guess I broke it and I cannot figure out what I did.

 local MarketplaceService = game:GetService("MarketplaceService")
 local buyButton = game.Workspace.BuyButton.ClickDetector
 local productId = 113601217

 buyButton.MouseClick:connect(function(player)
    MarketplaceService:PromptProductPurchase(player, productId)

 end)
 MarketplaceService.ProcessReceipt = function(receiptInfo)
    MarketplaceService.ProcessReceipt = function(receiptInfo) 
 for i, player in ipairs(game.Players:GetChildren()) do
    if player.userId == receiptInfo.PlayerId then   
        if receiptInfo.ProductId==113601217 then
        game.ReplicatedStorage.Card:Clone().Parent = player.Backpack



    return Enum.ProductPurchaseDecision.PurchaseGranted     
end
end
    end
    end
 end
