Put the weight ranges in a MySQL table and use the BETWEEN operator to retrieve the appropriate weight. Something like: fromweight, toweight, value 0,0.5,9.45 0.501,1.0,10.71 1.001,1.5,11.97 Then, the following SQL statement will pull the appropriate value: SELECT value FROM weights WHERE 1.3 BETWEEN fromweight AND toweight Much warmth, Murray http://www.planetthoughtful.org Building a thoughtful planet, One quirky comment at a time. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
