Foundation framework Challenge task 3 of 3

Task - http://teamtreehouse.com/library/nsdictionary-2 Let's add the year of the album to the 'albumMutable' variable. Where the key is a NSString 'year' and the value is also a NSString '1969'.

I've entered the following code but it gives me the error - "Bummer! The year set is not the correct value"

Is this a bug or have I done this wrong? Thanks

NSDictionary *album = @{@"title":@"Abbey Road", @"artist":@"The Beatles"};
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];
[albumMutable setObject:@1969 forKey:@"year"];
NSString *string = [album objectForKey:@"year"];

Hi Jack, try @"1969" forKey:@"year" instead of @1969, as this is a NSNumber and the question has been kind of "...and the value is also a NSString '1969'.".

Kind Regards Holger
