I am using ZenCart 1.3.7.1

I have an attribute "size" that includes 4oz, 8oz and 16oz sizes.
I set the weight field at .25, .5, and 1.
When someone orders the 16oz size, they are billed for two items instead of one evethough the item amount is 1.

I have reviewed my product entries and my attribute entries and have search the faqs.

I am at a loss for what to try next. Any help would be greatly appreciated.
