Anyone want to point me to why this isn't working: $hr_query = "select dp_lname,dp_fname,dp_id

                        WHERE dp_id NOT IN (SELECT sup_id FROM dir_title2)
                        ORDER BY dp_lname";

There are two tables, dir_all (the main list of everyone) and dir_title2 (supplemental). If someone is in dir_title2 then the sup_id is the same as their dp_id. What I am trying to do is get a list of every person in dir_all that is NOT in dir_title2. Any thoughts as to what am doing wrong? -- Kevin Murphy Webmaster - Information and Marketing Services Western Nevada Community College www.wncc.edu (775) 445-3326

Kevin, Looks like an older version of MySQL. Check your version: subqueries were not supported until ver 4.1. The older docs at MySQL give a work around.
