Hi Tera,

the complete solution for Challenge task 2 of 3 "Declare an NSMutableDictionary variable named 'albumMutable' that is initalized using the previously created dictionary named 'album'." should be:

NSDictionary *album = @{@"title":@"Abbey Road",@"artist":@"The Beatles"};
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];

Maybe you deleted the former task 1 of the challenge by mistake?

No, I just copy pasted the second line to have reviewed in forum because I already passed the fist task...which matches the line you typed...thus, the quiz has an issue with the second task which is the second line. I am starting to think the quiz compiler has issues cuz I just tried again and I got a Treehouse pop up window that it was unable to execute.

I just tested the Challenge part1 with

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

and part 2 with

NSDictionary *album = @{@"title":@"Abbey Road",@"artist":@"The Beatles"};
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];

and everything was ok.

Maybe you'd like to try again by refreshing your browser and C&P the above code?
