Database Query of table article_description not working

[mohawk]

I have added an extra field to the article_description table in phpmyadmin, now i can store information in this database and use it in the admin section but i cant seem to ouput the data in the meta_tags.php page.

My database query is

      $mt_articlecat_query = tep_db_query("select articlecat_name, articlecat_viewed, meta_tags from " . TABLE_ARTICLECAT_DESCRIPTION . " where articlecat_id = '" . (int)$current_articlecat_id . "' and language_id = '" . (int)$languages_id . "'");

$mt_articlecat = tep_db_fetch_array($mt_articlecat_query);

It outputs all the information fine accept my new meta_tag field.

My field names are slightly different than the oscmax default.

Thanks for any help you may be able to give
