I would agree with othell...@yahoo.com about the design...at least its
not clear.
In SQL Server 2005 this approach might work depending on the tables
design.

WITH Balance(Acct, amt)
AS
(
SELECT [group], amt FROM tbl_bal WHERE acct = 'A1000'
UNION ALL
SELECT G.acct , G.amt FROM tbl_bal G
INNER JOIN Balance B
ON G.[group] = B.acct WHERE G.acct <> 'A1000'
)
SELECT SUM(amt) FROM Balance;
