I cancelled a payment through PayPal. How do I update the payment for that charge? I looked at my payment information and it has my credit card information. I'm not sure where to update the PayPal part of payment.

I cancelled a payment through PayPal. How do I update the payment for that charge? I looked at my payment information and it has my credit card information. I'm not sure where to update the payment that was associated with my PayPal account? I am not sure what that paid for? I am trying to process updates on my IPhone & IPad for apps. I have already downloaded.
