are you trying to make sure an email is valid? if so this is what i use on my form that might help:

[code]    if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $email_address)) {
        echo "The email you entered is not valid. Please try again. <br/>";
exit();
    }[/code]
