Here is some portion for you... No i dea if its what you need to help:

    //  Get Members
    $members = $db->query_read("
        SELECT user.email, user.userid, user.username " . iif((!empty($vbulletin->options['c_news_letter_field'])),",userfield." . $vbulletin->options['c_news_letter_field'] . "") . "
        FROM " . TABLE_PREFIX . "user AS user
        " . iif((!empty($vbulletin->options['c_news_letter_field'])),"LEFT JOIN " . TABLE_PREFIX . "userfield AS userfield ON (userfield.userid = user.userid)") . "
        WHERE user.userid >= " . $vbulletin->GPC['startat'] . "     
        " . iif((!empty($vbulletin->options['c_news_letter_field']))," AND (userfield." . $vbulletin->options[c_news_letter_field] . " = '" . $vbulletin->options[c_news_letter_field_yes] . "' OR userfield." . $vbulletin->options[c_news_letter_field] . " = '')") . " 
        " . iif((!empty($vbulletin->GPC['usergroups'])), "AND user.usergroupid IN ('" . implode("','",$c_news_letter_filter_usergroups) . "')") . "
        ORDER BY user.userid ASC
        LIMIT " . $vbulletin->GPC['perpage']
    );
        
    while ($member = $db->fetch_array($members))

Just using: $member[field10] in the template doesn't show anything.
