I was actually playing with this a bit when your email arrived. :) I do have a suggestion for one portion here: > (literal ; Generated text on table title > "Table " > (format-number (ancestor-child-number "chap") "1") > "-" > (format-number (list-ref (element-number-list (list > "chap" "table") (current-node)) 1) "1") > ": " > ) > This could be done more simply with: (literal "Table " (format-number-list (element-number-list '("chap" "table") (current-node)) "1" "-") ": " ) Basically, you're unnecessarily calculating the chapter number with (ancestor-child-number), as this number is calculated for you by (element-number-list). Just have (format-number-list) concatenate the list returned by (element-number-list). And, in the interest of reusable code, consider this variation: (define (fmt-el-list elist #!key (fmt "1") (sep "-") (node (current-node))) (format-number-list (element-number-list elist node) fmt sep)) ... (literal "Table " (fmt-el-list '("chap" "table")) ": ") -Brandon :) DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
