[MP145]

I have this contact form that uses phpmailer, added captcha and some validation but when i click submit - Nothing Happens. I am not very sure what is wrong, some pointers please.

<?php
         function validate_email($email){

         $exp = "^[a-z\'0-9]+([._-][a-z\'0-9]+)*@([a-z0-9]+([._-][a-z0-9]+))+$";

                            if(eregi($exp,$email)){

                                if(checkdnsrr(array_pop(explode("@",$email)),"MX")){
                                return true;
                                }else{
                                return false;
                                }

                                }else{

                                return false;

                                }
                                }

    if (isset($_POST['Submit']))
                         {
    if (empty($_POST['nama']))
    {
    $errors[] = 'Please enter a name';
    }
    if (empty($_POST['email']))
    {
    $errors[] = 'Please enter an e-mail';
    }
    else if (!validate_email($_POST['email']))
    {
    $errors[] = 'Please enter a valid e-mail address';
    }
    if (empty($_POST['mesaj']))
    {
    $errors[] = 'Please enter some comments';
    }
    if (empty($_POST['validator']))
    {
    $errors[] = 'Please enter security code';
    }
    else if ($_POST['validator'] != $_SESSION['rand_code'])
    {
    $errors[] = 'Please enter correct security code';
    }
    if (count($errors) == 0)
    {
    $RepName = $_POST["nama"];
    $RepMail = $_POST["email"];
    $RepCom = $_POST["mesaj"];

    require("./phpmailer/class.phpmailer.php");
