  How is the page being rendered... meaning is it a page created in the admin, a static view file (no controller), or a controller/view?

  Controller / View. I'm bringing over a old CI site. Below is my controller.
  
  --
  
  <?php
  class Home extends CI_Controller{
  
  function __construct(){
  parent::__construct();
  }
  
  function Home()
  {
  parent::Controller();
  }
  
  public function index()
  {
  $vars = array('' => '');
  
  $this->load->module_library(FUEL_FOLDER, 'fuel_page', array('location' => 'home'));
  $this->fuel_page->add_variables($vars);
  $this->fuel_page->render();
  }
  }
  
  ?>

  Hmm... I tested this locally and am not able to replicate the problem (was able to see the merged in value). What happens if you just use:
  <?=$twitter?>

  No luck...I get the undefined variable error.
  
  In my Site Variables, I have the variable called 'twitter' which is active and no scope.
  
  BUT when I add "$vars['twitter'] = '@me';" to _variables/global.php, it works.
  
  Could it not be looking at the DB for this information? Is there a setting where I can change where Fuel looks?

  What do you have the $config['fuel_mode'] set to in you MY_fuel.php file?

  Great! Set it to auto since my page content will most likely be from view files but I want to manage my global vars in the admin area.
  
  Love the CMS, thanks for all your help!

  I am trying to do this same thing and am experiencing the same problem this thread originally voiced in that I am not seeing the value displayed on the view using the fuel_var function. I have my fuel_mode set to auto, but I have not added anything additional to the _variables/global.php file as mentioned above by ok1ha.
  
  What I want to do is quite simple. I have a Site Variable with a name of "Annual Gift Certificate Price" stored in Fuel with a value of 60. Plain and simple, it just stores a number.
  
  In my view file I have this:
  
  <?=fuel_var('Annual Gift Certificate Price')?>
  
  I'm using the controller method to render the view file, so this is not a fuel page I am trying to load. Also, if it helps, I am doing all of this from a custom module I created called "store".
  
  Thanks,
  Erik

  Try changing the site variable name to something like 'annual_gift_certificate_price' without any spaces. Also, you should be able to just do a regular merge without fuel_var like so to just test the variables existence in the view:
  <?=$annual_gift_certificate_price?>
