Need help sorting my results

[piznac]

This is the sql Im using in a recordset using dreamweaver

SELECT racer_name,SUM(points)
FROM race_results
WHERE `class` = 'gas'
GROUP BY racer_name
ORDER BY race_results.points DESC

Im really new to this but the "SUM" is working fine, but im having a problem with
ORDER By function,...its order by "points" which in my DB is a samllint ---- It just
needs to sort by that number (points) by largest to smallest,...any help would be
great!!
