For the fourth email address you add, it may look like this: http://site.com/confirm.php?id=4&c=182648 confirm.php grabs the id, checks the confirm code, and if all is well, resets the confirm code to 1 (true), or "yes", or whatever you choose. To get the random value, include this function that I just wrote for someone else in a different thread: <? function randNumber($min=1000,$max=99999) { // build a seed list($usec, $sec) = explode(' ', microtime()); $seed = (float) $sec + ((float) $usec * 100000); // seed random generator srand($seed); // return random number return rand($min,$max); } ?> Since the min is 1000, it will never be '1'. Hope this helps, Justin
