Are you kidding?…
If you have to delete Rows based on Criteria in separate (selectable) Fields you may write an A-script using this Algorithm:
1. Prompt the User to select a Category Item from the List as a pointer to a Range of Criteria Values.
2. Prompt the User to select one unique Criterion Value from the List.
3. Delete Rows from M1 matrix according to User-selected Criteria.
That’s exactly what I did. See Version of the A-script for such Case.
