    $msg= " <strong>Name:</strong> $name <br /> <strong>Contact:</strong> $contact <br /> <strong>Email:</strong> $email <br /><strong>Company:</strong> $company <br /><strong>Message:</strong> $message";
    require_once('mailer/class.phpmailer.php');
    $mail             = new PHPMailer();
    $mail->IsSMTP();
    $mail->Host       = "smtp.gmail.com";
    $mail->SMTPDebug  = 0;               
    $mail->SMTPSecure = "ssl";
    $mail->SMTPAuth   = true;                  
    $mail->Host       = "smtp.gmail.com";
    $mail->Port       = 465;                    
    //$mail->Username   = "me@domain.com";

    $mail->Subject    = "Enquiry from Website";
    $mail->MsgHTML($msg);
    $address = "balajeeenterprises9@gmail.com";
    $mail->AddAddress($address, $name);
    if(!$mail->Send()) {
      echo "Mailer Error: " . $mail->ErrorInfo;
