{employee} = "null" will only supress if the employee's name is "null". I don't know of anyone by that name....maybe in Europre somewhere?
IsNull({memofield}) should work, even with a memo field. While it is generally true that you cannot use a memo field in a formula, you should be able to conditionally suppress it based on an isnull() test as I have shown. I do not have a database with a memo field in it or I would test it.
