        return false;
    });
    $(".remove").live('click', function() {
        $(this).parent().remove();
    });
});
</script>

/* Do something with the data entered */

/* When the post is saved, saves our custom data */

function dynamic_save_postdata( $post_id ) {
    if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) 
    return;
    if ( !isset( $_POST['dynamicMeta_noncename'] ) )
    return;

if ( !wp_verify_nonce( $_POST['dynamicMeta_noncename'], plugin_basename( __FILE__ ) ) )
