NSString Task 3 incorrect value assigned to *favorite

Here is what I have. I've tried mixing all the variables into different locations and haven't been able to find something that will work. I guess I'm a little unclear on the syntax. I basically copied the videos NSString *concat = [[alfa stringByAppendingString:delta] stringByAppendingString:@"lotsmore"]; Follow up question: How did the instructor initialize "lotsmore" without declaring a NSString?

Forgot to actually include what I have. Here it is...

NSString *color = @"Purple"; NSString *preference = @"My favorite color is "; NSString *favorite = [[preference stringByAppendingString:color]];

You're using double square brackets where you should only have single square brackets: [preference stringByAppendingString:color]

Follow-up answer: the @ sign is a convenience notation for [NSString ...]
