MailChimp订阅PHP类表单合并字段

Question

Hi There I am using MailChimp Subscribe PHP Class Form by Tatwerat-Team ( link )

I am creatting a html form that uses PHP and a few others to create new subscribers on a mail chimp list.
It works fine when its just FNAME and EMAIL however as soon as I add in additional fields that validation breaks and Im not sure why?

The Form:

<?php
$config = array(
    #Mailchimp details
    "Mailchimp_ApiKey" => "API ID REMOVED FOR POST",
    "Mailchimp_ListID" => "LIST ID REMOVED FOR POST",
);
if ($_POST) {
    // First Name and Last Name Required
    require 'includes/MailChimp-Class.php';
    $MailChimp = new MailChimp($config['Mailchimp_ApiKey'], $config['Mailchimp_ListID'], TRUE);
    $MailChimp->subscribed($_POST['fname'], NULL, $_POST['email'], $_POST['pcode'], $_POST['tnumber'], $_POST['ntype']);
    echo '<div class="well">' . $MailChimp->message() . '</div>';
    $output = $MailChimp->message();
    if ($output == 'Thank you for subscribe our newsletter') {
        echo '';
    } else {
        echo 'There has been a problem. Please try again later';
    }
}
?>
<form class="subscribe" method="post" id="mc-embedded-subscribe-form">
    <div class="field">
        <input type="text" name="fname"  placeholder="Name" required>
    </div>
    <div class="field">
        <input type="email" name="email"  placeholder="Email" required>    
    </div>
    <div class="field">
        <input type="text" name="pcode" placeholder="Postcode" required>   
    </div>
    <div class="field">
        <input type="text" name="tnumber" placeholder="Telephone Number" required>  
    </div>
    <div class="field">
        <select id="ddl2" name="ntype" required>
            <option value="" disabled selected>Choose netting type</option>
            <option value="cricket">Cricket Ballstop Netting</option>
            <option value="golf">Golf Ballstop Netting</option>
            <option value="football">Football Ballstop Netting</option>
        </select>  
    </div>
    <div class="field">
        <button type="submit" title="Submit" class="button"><span> <i class="fa fa-arrow-right"></i> Download Now for FREE</span></button>
    </div>
</form>
<!--End mc_embed_signup-->
<script>
    $("#mc-embedded-subscribe-form").validate({
        rules: {
            field: {
                required: true,
                email: true,
            }
        }
    });
