Help with tables and for loops?

local shop = {creditshop:WaitForChild("10Credits"),creditshop:WaitForChild("50Credits")}


for _, v in pairs (shop[1]) do
    v.MouseButton1Click:connect(function()
        local passId = 21545568
        game:GetService("MarketplaceService"):PromptProductPurchase(player,passId)
        game:GetService("MarketplaceService").ProcessReceipt = function(receiptInfo)
            if Enum.ProductPurchaseDecision.PurchaseGranted and receiptInfo.PlayerId == player.userId then
                player.Credits.Value = player.Credits.Value + 10
                wait(1)
            end
        end
    end)
end
