    Conversion from string "" to type 'Date' is not valid

  • Hi RayClark,

    You cannot compare a string with a date.
    You can do this in several ways here is one:

    =IIF(Len(Fields!ReturnTime.Value)=0, "AliceBlue", "White")

    Use the length function to check the length of return time.  If it is 0 set it to alice blue else set it to white :).
