Mixed minimum option on and not working

I have 4 products that I am selling as mix or match with a minimum of 5 units. When I test the function I get an error code (Quantity Units errors - You ordered a total of: 1 Units: 5 ) to update the cart to a minimum of 5 units of each product even though the total quantity ordered is 5 pieces of the 4 different products. I have the mix set to yes.
I tried both this configuration:
Product Qty Minimum: 1
Product Qty Maximum: 0
Product Qty Units: 5
Product Qty Min/Unit Mix: Yes

And this one:
Product Qty Minimum: 5
Product Qty Maximum: 0
Product Qty Units: 1
Product Qty Min/Unit Mix: Yes

with the same result in the shopping cart area. What have I missed or what else do I need to do?

I have the current version of Zen Cart. I cannot find a troubleshoot answer in either the facts section or in past posts.

Check first if the Known Bug Fixes #24 at:

helps with this ...

NOTE: all of the bug fixes are a good idea to apply ...

Thanks. I made the bug fixes. I tried both configurations above and I still have the same results. Any idea what I am doing wrong?

You are testing 1 Product at a time, correct?

The minimum/unit/maximum settings are for each individual product and not for multiple different products ...

Have you an URL where we can see one of the Products that is not working correctly?

Hmmm. I want to sell the four different products with at a minimum of 5 units. The buyer can purchase any of the products to meet the minimum 5 units. Currently, the minimum of 5 works for each product separately but not any combination of all four. Is there a way to make this work?

That kind of discount where you are using multiple products is not built into Zen Cart ...

You might look in the Free Software Add Ons or the Contributions Forum for other types of Quantity Discounts ...

Thanks.
