I have been looking at the menu options and noticed the following.
If you add a quantity option to your menu this does not display correctly when placing an order. If the option costs £1.00 and you order 3 it still shows the cost as £1.00 and is not included in add to order total, unlike a check box for instance. (please see image-1)
Once added to the cart it does show correctly (image-2)
On the customer and admin order emails the option shows as =£1.00 when it should show =£3.00
