Error Question

[Ben Draut]

Can you help me understand what this means?

begin (possibly implicit): empty form is not allowed

  in: (begin)

There must be an implicit begin in my function, but I'm not sure what this means.

I'm doing something like this:

(define (lcs-length s1 s2)

  (define t (build-table ....))

  (get answer from t))

[Jay McCarthy]

You get that error when a function only has definitions in its body:

(define (f)
(define a 1)
(define b 2))

My guess is that your "get answer from t" is a definition or is really
inside the t's ()s but you can't notice because of indentation. If you
want to send it directly to me, I'm sure I could eyeball it.
