list = Product [Category == row.Category] sort by Product_Code ;
clear row.Items;
row.Items:UI.append(itemlist.Product_Code.getall())

ZOHO acknowledges that the code above at https://www.zoho.com/creator/help/fields/add-to-picklist-dynamically.html doesn’t work.  I’ve waited weeks in vain for support to get back to me with a solution.

Any ideas?  Thanks.
