Maybe you can use the function called GREATEST()...? <URL: http://www.mysql.com/doc/M/a/Mathematical_functions.html > Something like: SELECT count(ID),sum(greatest(pnt1,pnt2,pnt3,pnt4)) FROM wiseQuiz_questions WHERE test='$test' -- Roger --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
