new post graphic as bgcolor

[mr e]

ok i've been trying to make this hack but i dont know enough about mysql to get it done, what it does is instead of a new post/thread graphic i just want the background of the cell on the index.php to change color...i know this has to be in the index.php around the // do light bulb area, BUT the thing is i only want it to change color if it's a specific style, all the other styles would still have the graphic...this is what i have so far and i know im doing it wrong because for the life of me i cant get it to work

PHP Code:

$style=$DB_site->query_first("SELECT styleid FROM style WHERE styleid IS NOT NULL AND userselect=1");
        // do light bulb
        if ($bbuserinfo['lastvisitdate']=='Never') {
          if ($style['styleid'] == '5') {
            $forum['onoff']='#999999';
          } else {
                $forum['onoff']='on';
          }
        } else {
                    if (isset($bbforumview[$forum['forumid']]) and $bbforumview[$forum['forumid']]>$bbuserinfo['lastvisit']) {
                        $userlastvisit=$bbforumview[$forum['forumid']];
                    } else {
                        $userlastvisit=$bbuserinfo['lastvisit'];
                    }
          if ($userlastvisit<$forum['lastpost']) {
            if ($style['styleid'] == '5') {
              $forum['onoff']='#999999';
            } else {
                  $forum['onoff']='on';
            }
          } else {
                if ($style['styleid'] == '5') {
                  $forum['onoff']='#666666';
                } else {
                      $forum['onoff']='off';
                }
          }
        }
