Enter a Null Value through DAO 3.6

Hi...
I have a database program in which I would like the user to be able to enter Null value. It doesn't absolutly have to be that way... I could intercept a request to enter a Null value and insert a single Chr(32) (space). Then translate as Null upon request for read. But I though it would be perhaps a little cleaner if I could just add Null value to database. Thanks for your help.

Don't know if it will work but try using the Constant "vbNull" instead of the space.
