Your original post looked like you had done some grouping.
to get to testing the process I recommend you just get your data set with fields on the detail section.
now you can add a formual field that is the same as your select expert statement and place it on the detail section.
It should show TRUE for each row that would be included and FALSE for each row excluded.
What does your detail section look like for this testing and which rows are still showing as TRU that you wanted as FALSE?
