I am using CubeCart to collect reservations for a meal. Customers can choose starters (£7), mains (£16) and desserts (£7). The venue requires that the minimum order is a main course + one other. Currently I have set the product price to zero and the option prices to £7 or £16 as appropriate. The mains options are required, starter and dessert options are not. That gets the pricing right but doesn't enforce the minimum order rule. Is there any way I can fix this?
Many thanks
Graham
