Hi burrina
I have created another combobox. But was not that successful, as it was not bringing the related sub form entries. Therefore, I went for the check box solution again and was almost successful except that, when the row source of the combo box changes to new query, it shows StockID instead of StockName. So I get #Error in the sub form. It also affects the textboxes in the main form. I am attaching the latest version of the db for your support please.
