Hm... I'd prefer not having to hardcode things in the document. Here is a little attempt that gives strange results: (define (last-descendant-node nd) (if (node-list-empty? (children nd)) nd (last-descendant-node (node-list-last (children nd))))) And then I insert the following to get my number of pages: (element-page-number-sosofo (last-descendant-node (sgml-root-element))) Then I end up ROTFL when the formatted postscript reads "Page 1 of n" and so on. :) Did I miss something ? (appart from the potential possibility of getting a wrong number if the last-descendant-node computed spans several pages, that is) -- Yann Dirson <Yann.Dirson@fr.alcove.com> http://www.alcove.com/ Free-Software Engineer Ingénieur Logiciel Libre Free-Software time Coordinator Responsable du temps Informatique Libre
