Form submission on Wordpress not working ?

Hi Experts,


We have created a customized WordPress signup form in a page template. But when I hit the submission button the form is not submitting and I can't confirm the form submission is working. whenever I echoed back it's not showing. please see the below code

<?php

 /* Template Name:  signup-couple*/
global $current_user;
get_currentuserinfo();

  if (isset($_POST['submit']) {
    # code...
  
echo "am here";
$name = $_POST['name'];
$password = $_POST['password'];
$email = $_POST['email'];
$date = $_POST['date'];

echo $name;

if (($name != '') && ($password != '') && ($email != '')) {
    // TODO: Do more rigorous validation on the submitted data

    // TODO: Generate a better login (or ask the user for it)
    //$login = $firstname . $lastname;

    // TODO: Generate a better password (or ask the user for it)
    //$password = '123';

    // TODO: Ask the user for an e-mail address
    //$email = 'test@example.com';

    // Create the WordPress User object with the basic required information
    $user_id = wp_create_user($name, $password, $email);

    if (!$user_id || is_wp_error($user_id)) {
       // TODO: Display an error message and don't proceed.
      echo "<Script>alert('something went wrong');</script>";
    }

    // $userinfo = array(
    //    'ID' => $user_id,
    //    'date' => $firstname,
    //    'last_name' => $lastname,
    // );

    // Update the WordPress User object with first and last name.
    //wp_update_user($userinfo);

    // Add the company as user metadata
    update_usermeta($user_id, 'date', $date);
}

}
