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.
