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.

Try <dtml-unless expr="verify_close-date"> That will catch a null field
