I'm getting an sql error on the rankings page for the English Premier League. It is ok for the other league I have set up on my forum.

Here is what my error is:

Database error in vBulletin 3.8.8:

Invalid SQL:

SELECT
b.`userid`, `match_day`,
COUNT(*) AS `bets`,
SUM(`score_key`>0) AS 'evaluated',
SUM(`score_key`>0 AND `score_key` != `bet_score_key`) AS 'wr',
SUM(`score_key`>0 AND `bet_home`=`points_home` AND `bet_away`=`points_away`) AS 'rr',
SUM(`score_key`>0 AND CAST(`bet_home`-`bet_away` AS SIGNED)=(`points_home`-`points_away`) AND NOT (`bet_home`=`points_home` AND `bet_away`=`points_away`)) AS 'rd'
FROM `soccer_user_bet` b
INNER JOIN `soccer_match` m ON (m.`id`=b.`match_id`)
WHERE m.`league_id`=32 GROUP BY `match_day`, b.`userid`;

Has anyone got any suggestions on how to fix this?
