Hello ronwitty! Thank you for your post and apologies for the delayed response 😕 I am so sorry to hear that you were having difficulty adding a card on your PayPal account. This could be just a temporary issue and it could be simply be resolved by trying to add the card later on. Alternatively, if you are still getting an error message, the issue could be due to your card issuer or our internal security system blocking the card. You can read more about this here https://goo.gl/SmJtnJ. Hope this helps. - Carlos
