how are you doing it? can you show your query? is it from the same table or two different tables?
show us tables involved and structure.
u can make it a subquery
Select SumBreakMinutes, (select SUM(BreakMinutes) SumBreakMinutes from VBreaks vb where vb.ShiftID = vs.ShiftID)
From Vshifts vs
somthing like that I believe
