2. The price should write as it price per unit, per meter...or piece. The price calculation should be correct. This can be done with VM custom fields but. We have the example and will show you from one website.
3. Quantity - The client wants the user can write not just click with arrows (now is only possible to click with arrows. It should be enabled enter value).
