Yes. I don't think you can pay automatically out of your bank, unless you're using your credit / debit card. Correct me if I'm wrong - but if you want to pay using the funds on Paypal, there has to be funds IN your Paypal account. So, try googling around and find out how to transfer money from your bank -> Paypal. Then, life will be much easier and you'll be able to do whatever you want ^-^.
