Config variable only returning first letter?

[eluser]joehopkins[/eluser]
Hi,

I'm setting a variable to be used globally across the site so I thought I'd load a config file:

config/Sitevariables.php

Code:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$config['site_name'] = 'BAA CRM';

config/autoload.php

Code:

$autoload['config'] = array('email', 'Sitevariables');

anything.php

Code:

echo $this->config->item('Sitevariables', 'site_name')

Returns 'B'. Just the first letter.

What is going on?!!!! Why doth CodeIgniter forsake me so?

Thanks,

Joe
