@Sam_SAS , @Madelyn_SAS I've attached a picture of the table that I would like to filter. I would like to filter to just see Layover-New Station =1 or Layover-Removed Station =1. The code is similar for Layover-New Station/Layover Removed Station - Layover - Removed Station IF ( ( ( 'Layover - Current Month Count'n = 0 ) OR ( 'Layover - Current Month Count'n Missing ) ) AND ( 'Layover - Previous Month Count'n > 0 ) ) RETURN 1 ELSE 0 Layover - Current Month Count ParallelPeriod(_Sum_, 'Layover Count'n, _IgnoreAllTimeFrameFilters_, 'Effective Period'n, _ByMonth_, _ByMonth_, 0, _Full_, {Date}) None of my aggregated measures are showing up as filter options??? Thanks. Steve
