Oracle index with NULL values

[Selfors Bjørn]

Hi all!
(Axiant 3.1, Windows, Oracle)
I have added an index to a table (field includes null values), and I have added an access statement in my screen.  But when testing it, I get the error "Use SELECT to find NULL values" when I enter the TAB, planning to enter some value in the next request field.
How do I avoid this error?

mvh/regards
Bjørn Selfors,
