I'd like to create an order form for several products that are ordered as "one of" (e.g., if somebody wants to order, they're either ordering qty of zero or one). Can I have a checkbox on the order form (so that the customer just checks off the items she wants) and then the system is "smart enough" to realize that it's a quantity of 1, or do I need to use the quantity attribute of the product field?
(If it's the latter, can I limit the quantity to either 0 or 1?)
Thanks
Lawrence
