[Zope] Checking for nulls in a date/time field

[McDonnell, Larry]

Hi,

I thought I saw this before but I am having difficulty in findin gthis
answer. I use MS Access and can save the dates in their date/time format.
But if the field is empty (close_date) and I populated with a Null, how do I
find it?

I used this-

<dtml-if expr="verify_close_date=='Null'"> and I tried this <dtml-if
expr="verify_close_date==' ' ">. 

I'm just looking for a pointer, thanks.
