why is this array empty?

[sabret00the]

wondering why this won't work, the only bits that's not working is the commented out bit, i'm wondering just how it managed to wrong all of a sudden.

PHP Code:

if ($_POST['do'] == 'dogroups')
  {
      globalize($_POST, array('grpsaction'));
  
      foreach ($grpsaction AS $groupid => $action)
      {
          if ($action == 0)
          { // no point in checking the permission if they dont want to do anything to the group
              continue;
          }
  
          $confessionid = intval($confessionid);
  
          if ($action == 1)
          { // validate
              $DB_site->query("
                  UPDATE " . TABLE_PREFIX . "grps
                  SET approved = 1
                  WHERE groupid = $groupid
              ");
  
              //create grps_post row
                  //don't need to do this, it's done on the fly.
  /*
              //create grps_user row
              //select data from db
              $adduser = $DB_site->query("
                  SELECT *
                  FROM " . TABLE_PREFIX . "grps
                  WHERE groupid = $groupid
                  LIMIT 1
              ");
  
              //intravenous
              $DB_site->query("
                  INSERT INTO " . TABLE_PREFIX . "grps_user(groupid,userid,join_date)
                  VALUES ($adduser[groupid],$adduser[leaderid]," . NOW . ")
              ");
  */        } 


basically i'm trying to add data into the second table based on the $groupid

however the $adduser array seems to be empty.
