OK, I manged the way through to Paypal page by using the second obtion :

" - Checkout with PayPal. The safer, easier way to pay. "

after changing the setting of that method from Sandbox to live ! which was stupid from me that I should consider this as for testing purpose and that's why I set it the first time to Sandbox, but with the last method of paying with Credit card I still have a problem, I got this message:

10565 Merchant country unsupported. - The merchant country is not supported.


although I used my own info to fill in the cridet card fields but it didn't work ! What does that mean ?
