Hi

I have an expression for calulation of IDs. Given below is the expression

IF( Type = 'Error' AND

      Status = 'Yes' AND

       Condition3,

   Id,Null( )

   ) 

In condition3 i want to compare a Date Variable with two date values in such a manner that

Date is not in range (date1,date2). What is the helpful function or logic to achive this.

Kindly help
