Testing oobject for property

Hi to all.
I’m doing some exercises with JavaScript to understand its concepts, as outlined in Basic course. I’ve written this exercise, taking hints from part 90, but it doesn’t work. It never returns any Object property. Can you please help me to understand where the mistake is? Many thanks in advance.
