I have a problem getting a deluge script to execute in a sub-form when editing the parent form. 

I have a parent form that contains a sub-form (master-detail relationship).  I also have a deluge script that is intended to execute each time i add a row in the sub-form. The script executes well when creating a new record in the parent form. I am able to add as many rows as I need in the sub-form, and each time the script does execute as expected.  However, the problem lies in when editing the record in the parent form; when I press Add Row in the sub-form, the script does not execute.  I have two scripts; one located in "On Add Row" in the sub-form, and the other is located "on User-Input" on the first field in the sub-form.  Neither script is executing!!  

Any help to know what is going on!!

Thank you
