HAH, it worked!!!  i'll play with it -- i need it to now add a few more 
fields from each table, and then present them in order of (vnum, subnum) -- 
i also need to have it work from within access97 rather than from psql! but i seem to always start at psql and then
writethe same query in 
 
access97. . .   thanks much!!!

jt
