Views Problem

First off, great module.

I get the following error message when I try to create a view with sort criteria "Drupalit: Total Votes":

user warning: Unknown table 'drupalit_votes' in order clause query: SELECT DISTINCT(node.nid) FROM node node LEFT JOIN og_ancestry og_ancestry ON node.nid = og_ancestry.nid WHERE (node.type IN ('storylink')) AND (og_ancestry.group_nid = 1464) ORDER BY drupalit_votes.votes DESC LIMIT 0, 10 in /home/colossal/public_html/includes/database.mysql.inc on line 172.

Any ideas of what the problem could be?

Here is the view export code:

$view = new stdClass();
$view->name = 'test_stories';
$view->description = 'Lists the top stories for a particular group.';
$view->access = array (
);
$view->view_args_php = '';
$view->page = TRUE;
$view->page_title = '';
$view->page_header = '';
$view->page_header_format = '1';
$view->page_footer = '';
$view->page_footer_format = '1';
$view->page_empty = 'There are no stories for this group.';
$view->page_empty_format = '1';
$view->page_type = 'teaser';
$view->url = 'test-stories/$arg';
$view->use_pager = TRUE;
$view->nodes_per_page = '10';
$view->sort = array (
array (
'tablename' => 'drupalit_votes',
'field' => 'votes',
'sortorder' => 'DESC',
'options' => '',
),
);
$view->argument = array (
array (
'type' => 'gid',
'argdefault' => '1',
'title' => '',
'options' => '',
'wildcard' => '',
'wildcard_substitution' => '',
),
);
$view->field = array (
);
$view->filter = array (
array (
'tablename' => 'node',
'field' => 'type',
'operator' => 'OR',
'options' => '',
'value' => array (
0 => 'storylink',
),
),
);
$view->exposed_filter = array (
);
$view->requires = array(drupalit_votes, node);
$views[$view->name] = $view;
