Creating a data model code challenge question

Hi, I'm having a problem with part 3 of 3 on the creating a data model code challenge. I think I'm just missing something small but could not figure it out for the life of me.

ViewController.h
#import "UIViewController.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) NSString *shoppingCart;

@property (strong, nonatomic) NSArray *shoppingList;
@end
ViewController.m
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // Add your code below!

    self.shoppingList = [[NSArray alloc] initWithObjects: @"toothpaste", @"bread", @"eggs", nil];


    self.shoppingCart = [shoppingList objectAtIndex:2];
}

@end
