(define (subtract-1 n)
(string-append "Number is: " (number->string n))
(cond
[(= n 0) "All done!"]
[else (subtract-1(- n 1))]))
I keep getting the error: define: expected only one expression for the function body, but found 1 extra part. I'm not understanding why I'm getting this.
I did never write a lot of scheme, but it looks to me like you have one closing parenthesis to much in line 2.
rnlf is correct - i'd advise you switch to an editor with better brace-highlighting.
The interpreter is seeing '(string-append "Number is: " (number->string n))' as a complete statement (because it is), with the cond expression incorrectly trailing afterwards.

For some reason it wasn't enabled in For Beginners (only in General/Game Programming). I have enabled both prefixes in For Beginners.
