iOS Shopping Cart Challenge Not Working

I've passed with this up until this point. The error it's giving me is to remember that the array starts at 0 and then to assign it to a string named shoppingCart. My guess is I'm missing the assignment portion...?

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];

    self.shoppingList = [[NSArray alloc] initWithObjects: @"toothpaste", @"bread", @"eggs", nil];
    self.shoppingCart = [shoppingList objectAtIndex:2];
}

@end

You missed a self on the second shoppingList!

    self.shoppingList = [[NSArray alloc] initWithObjects:@"toothpaste", @"bread", @"eggs", nil];
    self.shoppingCart = [self.shoppingList objectAtIndex: 2];
