Khaos :: KhACL

[eluser]Stylec[/eluser]
Hi, I seem to be having a problem gettings this working.

I've set up the database and tables and can use the example code to create the objects in them, but when i run the code

Code:

<?php

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();    
    }
    
    function index()
    {
        $this->load->helper('Khacl');
            
        echo $allowed = kh_acl_check('neophyte', 'news', 'comment');
    }
}

I get this error

Code:

A Database Error Occurred
Error Number: 1054

Unknown column 'aro_node.lft' in 'on clause'

SELECT access.allow FROM khacl_aros AS aro_node, khacl_acos AS aco_node LEFT JOIN khacl_aros AS aro_branch ON (aro_node.lft >= aro_branch.lft AND aro_node.lft <= aro_branch.rgt) LEFT JOIN khacl_acos AS aco_branch ON (aco_node.lft >= aco_branch.lft AND aco_node.lft <= aco_branch.rgt) INNER JOIN khacl_access AS access ON (aro_branch.id = access.aro_id AND aco_branch.id = access.aco_id) WHERE aro_node.name = 'neophyte' AND aco_node.name = 'news' ORDER BY aro_branch.rgt ASC, aco_branch.rgt ASC LIMIT 1

Any ideas what I could be doing wrong?

Thanks
