Multiple Characteristics with 20 options each

We have a store that sells 20 different flavors of Balsamic Vinegars in 2 different sizes of containers. What we want to do is sell a 4 pack of each individual size, and have the option of the customer choosing 4 out of the 20 flavors for there individual 4 pack purchase. I have set up 4 different characteristic with 20 flavors on each one. The problem is, I can get 2 of these to publish, but if I try 3 or 4, I get a memory limit error. How do we set up 4 different options with 20 choices each for this type of sale?

Can anyone help me? Store is all ready to go live if I can just figure this part out. I have played with options but I just cant get that to work either.

Hi,

4 characteristics of 20 values, that's 20*20*20*20 variants to handle for the system.
You can't use characteristics for that.

Options could be a solution.

But the simplest solution will be to create 4 custom fields of the table "item" via the menu Display->Custom fields (Business edition). That will be simple to configure and won't induce any server load.

Awesome!!! Works like a champ now.
