i'm trying rank of spent hours table in amount of time. works. want restrict 1 usergroup. made this:

select     s.shortname servername, s.displaycolor displaycolor,     min(         if(`yearweek`=yearweek(current_date(),3) , (s.admin_group=u.usergroupid or find_in_set(s.admin_group, u.membergroupids)>0),             (select count(*)             godziny_tygodnie x                 left join vbulletin.vb_user xu on xu.userid=x.dbid             gw.sid=x.sid             , x.`yearweek`=gw.`yearweek` , x.`time` > gw.`time`)+1             , ( xu.usergroupid=s.admin_group or find_in_set(s.admin_group, xu.membergroupids)>0)         , null)     ) rweek0,     -- there more columns simillar previous, different time interval godziny_tygodnie gw     inner join godziny_miesiace gm on gw.dbid=gm.dbid , gw.sid=gm.sid     inner join godziny_lacznie gt on gw.dbid=gt.dbid , gw.sid=gt.sid     left join serwery s on s.id=gw.sid     left join vbulletin.vb_user u on u.userid=gw.dbid gw.dbid=:uid group gw.dbid, gw.sid

and gives me error column not found: 1054 unknown column 'xu.usergroupid' in 'field list'

why can't executed? vbulletin.vb_user.usergroupid exists...

problem wrong parenthesis. )+1 end of 9. line should on end of 10 line. works :)
