Hello,
I have created a setting page, workflow, and added some fields to a tab. Unfortunately, the setting fields aren’t showing. Below are the codes, would you let me know what’s wrong?

/* setting page */
function piklist_theme_setting_pages($pages) {
	$pages[] = array(
		'page_title' => __('OO Setting', 'oliveorange') ,
		'menu_title' => __('Theme Setting', 'oliveorange') ,
		'capability' => 'manage_options',
		'menu_slug' => 'oliveorange_setting',
		'setting' => 'oliveorange_setting',
		'menu_icon' => get_stylesheet_directory_uri() . '/piklist/parts/img/icon.png',
		'page_icon' => get_stylesheet_directory_uri(). '/piklist/parts/img/icon.png',
		'single_line' => true,
		'default_tab' => __('General', 'oliveorange'),
		'save_text' => __('Save Settings', 'oliveorange')
	);
	return $pages;
}
add_filter('piklist_admin_pages', 'piklist_theme_setting_pages'); 

Workflow:

<?php
/*
Title: General
Order: 10
Flow: OO Setting
Default: true
*/

File in setting dir:

<?php
/*
Title: General Setting
setting: oliveorange_setting
Order: 10
Collapse: false
Tab: General tab
Flow: OO Setting
*/
?>

<div class="piklist-demo-highlight">
  <?php _e('Text fields are at the core of most forms, and easily created with Piklist. Tooltip help can be added to any field with one line of code.', 'piklist-demo');?>
</div>

<?php

  piklist('field', array(
    'type' => 'text'
    ,'field' => 'text'
    ,'label' => __('Text', 'piklist-demo')
    ,'help' => __('You can easily add tooltips to your fields with the help parameter.', 'piklist-demo')
    ,'attributes' => array(
      'class' => 'regular-text'
    )
  ));

  piklist('field', array(
    'type' => 'textarea'
    ,'field' => 'demo_textarea_large'
    ,'label' => __('Text Area', 'piklist-demo')
    ,'description' => 'class="large-text code" rows="10" columns="50"'
    ,'value' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
    ,'attributes' => array(
      'rows' => 10
      ,'cols' => 50
      ,'class' => 'large-text'
    )
  ));

  piklist('shared/code-locater', array(
    'location' => __FILE__
    ,'type' => 'Meta Box'
  ));

Thanks
