• You are mixing up your aggregates and scalar values. You are trying to use a case expression to control the whole column. This doesn't work at all. It is awfully hard to figure out what you are trying to do here but here is my shot in the dark.

    SELECT ForcastUnitsTimesOMSCost, SUM(CTCBOHAndWCSBOHTimesOMSCost/IsNUll(ForcastUnitsTimesOMSCost, 0.00)) as Calculation

    FROM MyTable

    Where (CONVERT(date, GETDATE()) BETWEEN EventStartDate AND EventEndDate)

    Group By ForcastUnitsTimesOMSCost

    having IsNUll(ForcastUnitsTimesOMSCost, 0.00) < 0

    If that doesn't help you will need to provide us a few things:

    1. Sample DDL in the form of CREATE TABLE statements

    2. Sample data in the form of INSERT INTO statements

    3. Expected results based on the sample data
