I've installed the Minimum Order module, but have NO idea how to make it work with the way products are currently set up.

At the moment, products are set up as follows:

Category: Cookies
Products: cookie 1, cookie 2, etc.
Attributes: 1/2 dozen, 1 dozen

Need to set minimum order as 1 dozen (whether that is 1 single selected dozen or 2 1/2 dozen items)

Category: Brownies
Products: Brownie 1, Brownie 2, etc.

Need to set minimum order as 6 brownies OR any number of brownies if purchased with 1 dozen (or more) cookies)

ALSO I've seen reference in these forums to Mix: yes/no but I can't find it?

Thanks in advance for any help with this mind-boggling problem
