If the same trigger is present in Form, Block and Item level, normally the item level will fire first. How to change this default one. That is I want to fire the block level or form level. How to do this?

If same trigger is fired at form block, item item gets executed first then block then form. To change the process, change the trigger property execution hierarchy to "after" from "overridden".RegardsImran Baig
