What's wrong with this sql statement

I want the number of the plans that have an empty title. So a list of plans that have no title (yet).
I use this in an access query.

SELECT tblplans.plannumber,tblplans.title
FROM tblplans
WHERE IsEmpty(tblplans.title);

I'v made some empty fields but he doesn't show them in the query. I get an empty query.
Any of you know whats wrong?

Tx

Try

SELECT tblplans.plannumber,tblplans.title
FROM tblplans
WHERE tblplans.title is null

Or

Ok tx.

I used IsNull but not Is Null.
Damn spaces.

But thanks a lot.
