We need some sort of callout or message to show right above the grayed out PayPal buttons that tells people that they need to fill out the fields above the PayPal buttons, and check the terms and conditions box below the PayPal button in order to be able to use the PayPal checkout option.
Right now it's not intuitive, and we have at least 5 users contacting us about broken PayPal buttons, but the buttons are not broken, the person just did not fill out the fields above the PayPal buttons, and check the terms and conditions box below the PayPal button. This can cause customers to think the checkout page is broken, and not purchase the product.
