conditional format with Null data

[Irene]

In Access 2000, I want to changed the background of my field to red, if the
data is null. I know how to do it for an empty string, but not for null data. Do I need to change nulls to ""?
Thanks for the help.

Look up "IsNull" in Help. You should be able to apply whatever you're doing for an empty string using IsNull.
