Removing trailing comma in loop?

[RetroDreams]

Like so, right?

PHP Code:

$othervotes = $db->query_read("SELECT team, rankem_team.teamid, sum(points) AS totalpoints
FROM rankem_rank
INNER JOIN rankem_team ON rankem_team.teamid = rankem_rank.teamid
WHERE rankem_rank.weekid = $week
GROUP BY rankem_team.teamid
ORDER BY totalpoints DESC 
LIMIT 25,100");
if ($db->num_rows($othervotes) > 0)
{
while ($others = $db->fetch_array($othervotes))
{
eval('$otherbits .= "' . fetch_template('rank_otherbits') . '";');
}
}
$otherbits .= ', ' . trim($otherbits); 


Here it is in action... it duplicates the list and adds a space.
