Friends, I have a form with Controls 'StartDate' & 'EndDate'. I wish the user to enter either a start date or end date or both as long as 'EndDate'>='StartDate'.
The Validation Rule for the 'StartDate' control is =([StartDate] Is Null) Or ([EndDate] Is Null) Or ([StartDate]<=[EndDate]) - Thisworks.
But if I try the same validation on the 'EndDate' Control it always displays my validation Text even if' StartDate' is null.
Why?
Appreciate it as always.
