Problem on the Code Challenge task 3 of 3

Finally, we need to save these changes up to the Parse back-end. The relation is part of the 'playlist' property, where 'playlist' is an instance of PFObject. Save 'playlist' in the background to save the changes to the relation (don't worry about using any blocks).

What's wrong with my try below.

#import "FavoriteMoviesViewController.h"

@implementation FavoriteMoviesViewController

- (void)addVideoToPlaylist:(PFObject *)video {
    // Add custom code below!
    PFRelation *relation = [self.playlist relationforKey:@"videos"];
    [relation addObject:video];
    [self.playlist saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (error) {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];


}

@end

Don't worry about the block. Just use saveInBackground instead.
