The search page still has some glitches. Doing searches based on date-range works well, but doing searches by Student ID or Student Name don't work. Please see private message below. This time I haven't added or deleted anything on the page. The page is just as you left it after updating the trigger. I just hadn't tried doing any search based on Student ID or Student Name.
Update: I just saw that the trigger for the search is set to: isset($_GET["S_date"]) && $_GET["S_date"]. Wouldn't that mean that only the date fields trigger a search and that none of the other fields do?
