Right you are Tony, Selling units not dispensing units.
Also, as you say Tony, product selection not a player here. This is just to assist in the act of quantity entry. In our practice Tim, we measure the effectiveness of our product naming convention by the fact that we hit a unique item without every seeing the product selection dialog, hence our vets often will never see the product description whilst billing.
Also just a point of clarification, the spec refers to the adding it to the label dialog but should also include the billing dialog. I attached two mock up screenshots of the proposed change.
