[plugin: Woocommerce] ECHO and custom fields help needed…

I have a couple of custom functions and I do not know what PROPER php code I need to have in order to get them to echo on two main template files:

admin-new-order.php and customer-processing-order.php files…

My Functions.php file from my child theme:

add_filter( 'woocommerce_shipping_fields', 'wc_npr_filter_company', 10, 1 );

function wc_npr_filter_company( $address_fields ) {
$address_fields['shipping_company']['required'] = true;
return $address_fields;
}

/**
 * Add the field to the checkout**/

add_action('woocommerce_after_order_notes', 'social_good_field');

function social_good_field( $checkout ) {

    woocommerce_form_field( 'social good', array(
        'type'          => 'select',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Select Charity To Donate Part of Sale'),
		'clear' => false,
		'options' => array(
		'ASPCA' => __( 'ASPCA', 'woocommerce' ),
		'PetsMart' => __( 'PetsMart Charities', 'woocommerce'),
		'The Humane Society' => __( 'The Humane Society', 'woocommerce'),
		'he Broward Humane Society' => __( 'The Broward Humane Society', 'woocommerce'),
		'American Humane Association' => __( 'American Humane Association', 'woocommerce'),
		'Other' => __( 'Other', 'woocommerce'),
		),
        ),

		$checkout->get_value( 'social good' ));
}	 

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'social_good_field_update_order_meta');

function social_good_field_update_order_meta( $order_id ) {
    if ($_POST['social_good']) update_post_meta( $order_id, 'My Social', esc_attr($_POST['social_good']));
}

/**
 * Add the field to the checkout
 **/
add_action('woocommerce_after_order_notes', 'my_custom_checkout_field');

function my_custom_checkout_field( $checkout ) {

    echo '<div id="my_custom_checkout_field"><h2>'.__('Other Charity').'</h2>';

    woocommerce_form_field( 'my_field_name', array(
        'type'          => 'text',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Type in the name and email address of the special charity you want a part of the sale to go to'),
        'placeholder'       => __('charity name and email'),
        ), $checkout->get_value( 'my_field_name' ));

    echo '</div>';

}

/**
 * Update the order meta with field value
 **/
add_action('woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta');

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ($_POST['my_field_name']) update_post_meta( $order_id, 'My Social Field', esc_attr($_POST['my_field_name']));
}

/**
 * Process the checkout
 **/
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    global $woocommerce;

    // Check if set, if its not set add an error.
    if ($_POST['social_good'] == 'Other' and !$_POST['my_field_name'])
         $woocommerce->add_error( __('Please enter charity and email into text .') );
}

I tried these ideas and this did not work:

<?php echo get_post_meta( get_the_ID(), ‘My Social Field’, true ); ?> <?php echo get_post_meta($post->ID, ‘My Social Field’, true); ?>

some help over here….
