}

Can you explain why I am having problems with the cardtype? This is homework.

What problem are you having with the cardType? Is it possible that the one before it, the hidden value, is actually the problem? Maybe it is null.

Check your database fields, make sure there is a field called cardType and it is spelled exactly the same.
