Well, it looks like for the second error thick has not been defined.  And
I would guess (although I don't know for sure, because there's not enough
code shown in your mail) that width is not defined in the first case.
(width (/ 2 slope)) should be used inside the bindings section of a let
block; if it's outside of that context, you're trying to evaluate a
procedure called width.  A likely source of that error would be an extra
right parenthesis on the line above the line that generated the error.
