GROUP by clause, /sub query problems

I'm trying to list salesreps (if they have any sales for a particular date) with their total sales amounts for a queried date, but when running this sql string in QueryAnalyzer, it says there is an error with syntax on Line 1 near "s" :
SELECT o .Rep_ID, o .ID, s.ID, SUM(b.orderamount) AS totalsales, b.order_ID

FROM (SELECT b.Deal_ID

FROM btransactions b

WHERE b.BoardDate = '20050815') SalesReps s INNER JOIN

orders o ON o .Rep_ID = s.ID INNER JOIN

b ON o.ID = b.Deal_ID

GROUP BY d .Rep_ID, d .ID, s.ID, b.order_ID

HAVING (SUM(b.orderamount) > 0)
?

You have a space character following your "o" table alias throughoutyour query. Remove that extra space whereever it appears and seeif that clears up your problem.
