How to check if a Date Field in a Eletronic Form is null or not set ?

Cibim

Hi,

I need to check if a Date Field in a Eletronic Form is null or not set, like 1/1/0001 12:00:00 AM, to show/hide another field, using Forms Builder rules.

I've tried this:

1- myDateField != ""

2- myDateField != "1/1/0001"

3- myDateField != "1/1/0001 12:00:00 AM"

But did not work.

How to do that?

Thanks.
