Conditions not working properly???

Hi,

I have created a Calc KF to check whether Cost is less than zero. It provides me the desired results (case 1).

When I use this boolean value in a condition (case 2) to provide me with only values less than zero (Boolean value Condition = 1), it does not provide me the right results. The number of records having Boolean value = 1 in both cases differ.

I am not sure why this is happening. Please provide any insights.

Thanks and Regards

Andy.
