Am I missing some syntax?

From what I can tell I have followed the syntax for adding an object to a mutable dictionary, yet I am told that the year set is not correct, thought it is exactly what it says to make it. or am I just losing my mind!

nsdictionary.mm 
NSDictionary *album = @{@"title":@"Abbey Road",@"artist":@"The Beatles"};

NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];

[albumMutable setObject:@1969 forKey:@"year"];

You almost had it. You just needed some quotes around your NSString for 1969.

nsdictionary.mm 
NSDictionary *album = @{ @"title": @"Abbey Road", @"artist": @"The Beatles" };

NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];

[albumMutable setObject:@"1969" forKey:@"year"];
