Query engine error

Can anyone tell me why I am getting this error when I try to view my report:
Query Engine Error: '21000:[Microsoft][ODBC SQL Server Driver][SQL Sever]
Subquery returned more than 1 value. This is not permitted when the subquery
follows =, !=, <, <=,>,>= or when the subquery is used as an expression.
thanks in advance!
It would help to see your query.
But I expect that it is something like:
Select (select col from tbl where key = topkey) as subcol
from toptable
If the subquery could return more than one value, the query will error out.
