I reattached a revised workbook and below are the screenshots. I also changed your Call Type to not be 'Exclude', but to be a simple filter. Just select Inbound to see results for that portion of the calc or Outbound for that portion of the calc. If this answers your question/issue, please mark this response as correct. Thx! Don

Selected on Inbound and the underlying data shows only those call seconds under 10:
Selected on Outbound and the underlying data shows only those call seconds under 30:
