Error with article variant

Hi,
i want to use the plugin Stockable Variants in the Virtuemart component to give to the users the possibility to choose color and size.
But i have a problem with the article layout as you can see in the image attached.
How can i fix this showing only the base price?

Thanks

In the product page i need the fix the layout.
I'd like to put the tab "Ask a question...." near to "Add to cart" like in your demo but with the variants something happened (as you can see in the image attached).
How can i fix it?

Thanks
Vito Magno

You need to edit:

templates\hot_drug_store\html\com_virtuemart\productdetails\default.php

Can you please help me.
I don't understand what do i have to change to fix this.
I also have to increase the size of the button "Add to cart" because, as you can see in the attached file, it needs more space in italian.

Thanks
Vito Magno

That would count as custom job (modifying original product by customer needs).
