I just installed this Mod and seeing one issue. I tried searching this forum but can't find an answer.

I have one attribute 'size' for all of my products as radio button. When I add a product to the Cart it does not require the 'size' option to be chosen and thus I'm able to add a product to the Cart without size. How do I make the size attribute as required. I tried the Attribute flag 'required for text' but it did not work.

Any help on this would be great
