After using the button build app, the paypal buttons for the single-select list do not open. They open in the review section of the button builder but not when I copy the code into the website. After the PayPal button is clicked, it flashes briefly and then goes back to the button display. The button for the fixed price opens, allowing the buyer to complete the payment; but not for a single-select list one. Each of the buttons displayed flash upon being clicked. The button for a credit card or debit card doesn't do anything. Why isn't this working? Do the single-select type buttons require additional permissions?
