Whats wrong with this SQL code?

[Millenium IT]

$user_f_rep = $vbulletin->db->query_read("SELECT COUNT(reputation.reputationid) AS reps, SUM(reputation.reputation) AS replevel, reputation.userid
					FROM " . TABLE_PREFIX . "reputation AS reputation
					LEFT JOIN " . TABLE_PREFIX . "user AS user ON (reputation.userid = reputation.userid) WHERE reputation.userid = $vbulletin->userinfo['userid']
					");

I keep getting database errors when I implement this plugin that im busy making. Its on forumhome_complete. any ideas? could you tell me where my flaw is?

--------------- Added [DATE]1197838558[/DATE] at [TIME]1197838558[/TIME] ---------------

Ok, I changed the codes a bit, got rid of the database error but now im getting a message where the variable is implemented in the template system reading"Recourse id #49"

this is the code im now using:

$user_f_rep = $vbulletin->db->query_read("
						SELECT (reputation.reputation), reputation.userid
						FROM " . TABLE_PREFIX . "reputation AS reputation
						left join " . TABLE_PREFIX . "user AS user ON (reputation.userid = user.userid)
						WHERE reputation.userid = {$vbulletin->userinfo['userid']}");
