I'm throwing a warning on a function I created. I thought a & in front of the argument was supposed to make it optional. Is there something else I need to do make that argument optional? <CODE> //I simplified the code function doEmail($username, &$link) { if (isset($link)) { print "$link $username"; } else { print "$username"; } } doEmail($arg1); doEmail($arg1, $arg2); </CODE> Here is the error: Warning: Missing argument 2 for doemail() in /srv/www/htdocs/test-a/staff/email_scramble.php on line 24 thanks in advance for any help. -- D.
