I can not complete my payment ! Problem is about adding credit card/debit card or similar things..

Unfortunately, we can't process your payment. Here are your options:

• Check out with another PayPal method, like the one we're showing now.
• Select a different payment option.

That's my problem. I tried some credit and debit cards but still can not complete my payment. I can see the money on my paypal account but I do not know why cant I pay? Actually I cant understand why do I have to add a card? If I want to use any card I use, why do I use Paypal? 

Thanks.

Normally you can use funds in your Paypal balance if they are cleared and not pending and in the correct currency.
There may also be other reasons why you cannot use your balance when you make a transaction. For example, Paypal state that to provide one of the safest online payment methods their security program considers a variety of factors at each transaction to keep users safe.

Occasionally, they change a payment method as a matter of security. So sometimes a funding source may be unavailable at the time of the purchase. Paypal would not be able to manually change the security settings. However, you can try clearing your cache and cookies, deleting your browser history and waiting for 48 hours without accessing your account to let the system reset and try again.
