If you have to write 'min', you can.

(define (min a b)
  (if (< a b) a b))

"Define the function 'min' as a function of two variables, a and b. If
a is less than b, return the value of a. Otherwise, return the value
of b."

If you want to come to a better understanding of how to manipulate
data in Scheme, I highly recommend working through HtDP
(http://www.htdp.org/). The lessons you learn through working through
that material will serve you very well with Fluxus; the first nine
chapters (they're short) introduce you to different kinds of data, and
how to write functions that manipulate that data. That, and the PLT
Scheme mailing list is a good place to ask for help if you get stuck
working through said material.

Cheers,
Matt
