Hi! I am Renato from Brazil

In the exercise 16.2.5, I cannot solve the problem, 
because I don't have any idea how to work with the error messages.

"dir-content: expects argument of type <struct:dir>; given (list (make-dir 'Text (list 'part1 'part2 'part3)) (make-dir 'Libs (list (make-dir 'Docs (list 'read)) (make-dir 'Codes (list 'hang 'draw)))))"

What do you suggest?


Windows Live Messenger. O melhor em multitarefa.
