How to reload element from child

How to reload a field on parent window from opener?
I have a field tyle select and I would like to reload it from opened child window.

The sc_master_value macro can update a field on a master form from a child form, but it will only update the select field to a value that is already on the list. Is that what you’re trying to do or do you need to refresh the query to change the items on the list?
