ISBLANK doesn't return to TRUE when the value returns to empty

ISBLANK works when I open the app and the space is empty, when I fill it it returns me a False as it should work. But when I leave the space empty again, it keeps refreshing me FALSE instead of TRUE.

Hi @Hern-ec53, welcome to the community! :honeybee: :honey_pot: Thank you for raising this with us.

I tried this out, and I'm seeing the same behavior as you've described; I'm passing this along to our team to address. For a solution now, you can use ="" instead of ISBLANK to validate if the field is empty or not. It would look like: $[DataCell1]=""

Hope that helps, and thank you again for bringing this to our attention. :slight_smile:

Just adding onto @Alyssa:

Cleared datetime fields default to 0 instead of "", so you need to use $[DataCell]=0

I've been using OR(ISBLANK($[DataCell]),$[DataCell]=""), which has been working for the most part.
