        // Captcha check
        $t = trim($HTTP_POST_VARS['verify']);
        if ($t == "") {
                $captcha_error = "Enter the verification code!";
                $error = true;
                $messageStack->add('contact', $captcha_error);
        } else if (trim($_SESSION["thecode"]) == "") {
