Carl beat me to it on this one.

Two more tricks you can do to simplify your life:

1) Always write parens in pairs, then fill in what goes inside them.

2) Add newlines to make it clearer what goes with what.  This isn't
the "done thing" in Scheme, but it's a useful tool while you're
learning.  So:

(define (foo a b (c 7))
  (let (
          (x a)
      (display a b c)
)) ; let and define

A decent editor will handle the alignment for you.
