objectAtIndex questions

I'm pretty sure I'm doing this challenge correctly but it keeps coming back with an issue. I'm not sure why this wouldn't work. Any help?

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

The challenge is to create an array, then create a string and add the 3rd item in the array to the string.

Thanks in advance!

Hi Judah,

When setting *bookTitle to the third index of the *booksArray, you don't need to do a self declaration. The above code will validate.
