There is an error in the statement (define sx (+ (* 2 (+ pad dpml N)) d-1)).
Do you mean that sx = 2*(pad+dpml+N) + (d-1)? Then the correct statement is (define sx (+ (* 2 (+ pad dpml N)) (- d 1))) If you mean something else, remember the expressions in CTL is different from the natural way to write them, and they have their own syntax.
