Yes, the other bookid check was missing. I only have two problems now.
1. I don't always have 2 authors, if I only have 1 then I don't
get that book at all.
2. I can't be sure what the maximum number of authors is either. I could
of course make the maximum pretty large, but then it does become
somewhat tedious to code the SQL statement. Could this be easily made into a
function where the maximum authors is passed to it?
Thanks for the help.
