Name field appears, but not in actual list

Hi Lap, for some reason I had to add the code in the Functions again, and although the code looks right, and the name field appears, the name won’t register in Mailchimp.

See it here: https://bloggbar.no/

Have I forgotten something in the code? It looks like this:

add_action( 'mctb_before_email_field', function() {
    echo '<input type="text" name="*|FNAME|*" placeholder="Fornavn" />';
});
add_action( 'mctb_before_email_field', function() {
    echo '<input type="text" name="*|FNAME|*" placeholder="Fornavn" />';
});

add_filter( 'mctb_data', function( $vars ) {
    $vars['*|FNAME|*'] = ( isset( $_POST['*|FNAME|*'] ) ) ? sanitize_text_field( $_POST['*|FNAME|*'] ) : '';
    return $vars;
});

Thank you for any help.
