Variant quantity issues

Hello,

I am advancing along with hikashop and getting to know it better to where I can really use and modify it.
But I have a serious problem now.

When I have a product -- a pair of shoes -- with only one list of variants -- size -- and I change the variant from the dropdown menu, it does not modify the product. If I continue to checkout it allows me to checkout without any warning. Also if I try to checkout with a variant that is out of stock -- has a back-end quantity of '0' -- it also allows me to purchase the product.

Here is a link to the product page -- dni-tango.com/us/store/online-store/prod.../category_pathway-13 .

Is there some kind of pop=up that happens when someone tries to select a product that is not in stock. I would like some warning to appear and an invitation to write me to make a special order. Does hikashop offer something like this?

Thank you

I have updated to the latest version. Still no luck.

this is the link in my browser.

I did indeed change the product show view. But I only reordered the code -- as you helped me do yesterday in another thread.

I have attached a screen shot from how I currently see the page.

Would you like me to attach the product show view?

I have changed back to the defult css file. But has not changed the status of the problem. The variant still goes to the configured default size but doesn't change anything when I select another variant.
