Good Evening support and Everyone,
I am trying for some time to create a calculated field in a table on a Portal. I can add an Action but not any condition.
This table has the aim to gather all certificates of equipment and this calculated field should calculate time left to expire.
then i'll check what is the best way to issue some email alerts when this date is reaching.
As soon as I click on add a CONDITION, it is getting me this set up, and it seems that I can't change it.

Any one can help me on this subject?
Thank you in advance.
