=IIF(Fields!Category.Value = "Actual" AND Fields!Periodic.Value <5,"red","black")
Maybe with
=IIF(Fields!Category.Value < Fields!Periodic.Value ,"red","black")
?
If actual is less than budgeted I would think that is a good thing. I would highlight it red if it were say >10% over budget or something similar. Just my two cents.
