Minimum quantity, combination of sizes

Hello, I'm trying to set up my shopping cart so that the customer has to buy a minimum of 36 T-Shirts but they can have a different combination of sizes. For an example someone could but one style of a T-Shirt and have it in 6 smalls, 6 mediums, 12 larges, and 12 extra larges, thus meeting the 36 minimum requirement.

Is there anyway to do this?

Set the Product Minimum to 36 and the Mixed to YES ...

After changing the option to YES I did a little test purchase, with 6 small, 6 medium, 12 large, and 12 extra large. The result was a total of 36 but I got this error message:

Please update your order. The item: Burst Camo, has a minimum quantity restriction.
You ordered a total of: 30 Min: 36
The item: Burst Camo, has a minimum quantity restriction.
You ordered a total of: 24 Min: 36
The item: Burst Camo, has a minimum quantity restriction.
You ordered a total of: 12 Min: 36

But this doesn't make sense because it also says this:

Total Items: 36 Weight: 18lbs Amount: $143.64

There could be an issue with that very old, and buggy version of Zen Cart that you are using ...

I have not used it in forever and do not recall if that issue existed or not in v1.3.8a ...

It's great, i'm finding it
