Don't post images that contain your credit card number, these are user public forums, not iTunes Support nor Apple - I've asked the hosts to remove it, but as you posted it for the world to see you should consider getting the card cancelled and replaced.
If you are getting a message about having too many cards on the account either try one that you've already used, or try contacting iTunes Support and see if they can/will reset the count/limit on the account : https://www.apple.com/emea/support/itunes/contact.html
