<?php

  function demo_type_tax($taxonomies) {
     $taxonomies[] = array(
        'post_type' => 'piklist_demo'
        ,'name' => 'piklist_demo_type'
        ,'show_admin_column' => true
        ,'configuration' => array(
          'hierarchical' => true
          ,'labels' => piklist('taxonomy_labels', 'Demo Type')
          ,'hide_meta_box' => true
          ,'show_ui' => true
          ,'query_var' => true

  }

Why was the parentheses deleted from line 19? Doesn't seem to match up now?
