PayPal offers different kinds of accounts. To guide on Nonlocal, you must have a free business account. This is required in order to process credit card payments from guests that do not have PayPal accounts.
If you don't already have a business account, upgrading you existing account or creating a new PayPal business account is quick and free of charge. There are no additional costs involved.
To upgrade to a PayPal business account, go to http://www.paypal.com/upgrade. If you are an individual, just enter your own name when PayPal asks for a "business name".
