Error Message when Deleting Credit Card

Hi There,

I need to delete a fuel card that was added as a credit card in error. Before I can remove the card, I have to unlink it. The steps to unlink as per Sage are to select the "used" cards option, click on the name of the card to be deleted and hit backspace, then the payable account, hit backspace and last the expense account and hit backspace. When I follow these steps and select "ok" I get an error message that says "The name was not entered. The credit card must have a name".

Please help...what am I doing wrong?!
