I'm assuming you're trying to use PayPal balance, which yes, is supported by the store the last time I checked. If it says that you need to add a payment method, then I don't think you setup your PayPal payment methods correctly. I suggest googling how to add PayPal balance to your payment methods. If that still doesn't work, and you've tried absolutely everything, I would suggest you contact PayPal support.
