self.booksArray would only work if you had already created the property in your header file for booksArray. Since it doesn't you need create the pointer to booksArray and the initialize it. So it would look like:

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];

Same challenge or a different one? You might want to go back and complete the intro to C course to help you get a better understanding of all of these concepts. They are crucial to understand.

the full set of answers to this challenge is

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
NSString *bookTitle = [booksArray objectAtIndex:2];

the reason its not workng is because you need to create a new NSArray object, and not use a property. try

NSArray *booksArray = [NSArray arrayWithObjects:@"Hamlet", @"King Lear", @"Othello", @"Macbeth", nil];
