Hello guys,
I have a problem in the trigger Post-Change "Item-Level". I want this trigger to Trigger only and only when a change happens in the Field. The trigger seem to Trigger whenever there is an execute_query.
My Idea is:
Whenever the field is changed check the entered value. Why can't this trigger work as I need ?

Unless I'm wrong, POST-CHANGE is (was) there for backward compatibility with older Forms version(s) (such as 3.0). Nowadays, you should use
- POST-QUERY (which fetches non-database items values after querying the data block)
- WHEN-VALIDATE-ITEM (used to validate values you enter)
Both should, basically, contain more or less the same code which regards populating non-database items.

Answering your question strictly, it is the WHEN-VALIDATE-ITEM you're looking for.
