NULL value

How do I determine if a calculation produces a null result. Eg: I have a calculation max(field1). If no data has been entered in field1 this should return null. How do I test for this? I tried using null and ""; neither worked.

Cheers.

ression returns empty, e.g. = 

IsEmpty ( Somefield )




Or you can test if an exp
IsEmpty ( Max ( Field 1 ) )
