Once again with PHP, you don't need to get too complicated. I've had nothing but problems with array_rand() in a baseball management game I'm working on, needing only one entry at random from a list of given choices several times per page. Instead of array_rand(), I came up with this: // list of options (shortened due to manual's word wrap) $teamcolours = array("green","red","orange","blue","purple","grey"); // retrieve one of the options at random from the array $teamcolours = $teamcolours[rand(0,count($teamcolours))]; // print to verify it works print $teamcolours; it works like a charm. remember to seed the random generator - srand() - at the top of your script. -- http://www.php.net/manual/en/function.array-rand.php http://master.php.net/manage/user-notes.php?action=edit+26884 http://master.php.net/manage/user-notes.php?action=delete+26884 http://master.php.net/manage/user-notes.php?action=reject+26884
