How do I print off a shipping label, paypal will not let me add 2 card to my account?

[winterbliss90_0]

Hey, so I sold my items and I am currently trying to print off the shipping labels. However each time I fill out the label, I get directed to paypal and am asked to add a card to my account (it says I am suppose to have 2 on my account) but it will only let me add either a visa or a debit card but not both? Please help, I'm new to this and don't understand.

I'm not exactly sure where the error lays. Paypal will want a credit card on your account PLUS a link to your actual bank account, not a debit card.
