I have a report that I need to change the background color (ex. gray) if the Day falls on the weekend (highlighted) in yellow. Have the code below that I have placed in row fill, but did not work. The yellow is manually colored.
iif((weekday(Fields!row_date)=6 or Fields!row_date=7s!TranDate=7) TranDate=Nothing),"LightGrey","Transperent")
