  <p>Hi, This one worked in the past and its deployed but all of a sudden it is started throwing an error.
   In the Tablix properties I have to check these 3 conditions =IIF(DATEDIFF("d", Parameters!startDate.Value, Parameters!endDate.Value) > 30 AND Parameters!startDate.Value > Today() AndAlso Parameters!endDate.Value > Today() AND Parameters!startDate.Value >= Parameters!endDate.Value, True,False) . If I choose end date as todays date it is throwing a message but it is also displaying data. Please help me. It worked earlier, it used to show only message saying date is future date. Now it is displaying data also. I don't want the data to be displayed. TIA.</p>
