Credit Card Payments

Credit Card Payments

Maybe this is a stupid question, but I can't figure it out. I have an HSBC credit card. When I initially signed up to make online payments I just provided my checking account number to have payments taken out of that account. Well, my dad called and said that I can use his credit card to make a payment of my tuition bill. I had already paid that off so I was just going to use his hard to pay off a bit of my credit card balance. So when I go to the website to make a payment it just has my checking account info on there and doesn't give me an option to choose another method of payment (ie my dad's credit card). So I go to "update banking info" and if gives me an option to add another bank account but not a card. My question is.. is it possible to make a credit card payment with another credit card? If so, how?
