Can't display item from an array

Yes, that is the problem, I want to complete the borrow function.

Can you help me?

I belive I can help you(ate least i´ll try). Unfortunately I don´t have much time, but for now I realized that you don´t use the list of member when you borrow a book, you could pass the list as a parameter. Then you could register the borrowed book in the members list.
