I have a form Items, and form Recipe with a subform.

In my subform I need to populate a dropdown box based on the item selection.

row.PurchaseTxt=Items [ID == row.items].Purchase_Txt;

row.InventoryTxt=Items [ID == row.items].Inventory_Txt;

row.UsageTxt=Items [ID == row.items].Usage_Txt;

clear row.Usage;

row.Usage:ui.add(Row.PurchaseTxt);

row.Usage:ui.add(Row.InventoryTxt);

row.Usage:ui.add(Row.UsageTxt);

Any help would be appreciated.
