Cart not working in product details

[ilsanto]

Hello everyone, I use joomla 3.4.1 and  virtuemart 3.0.6.4.
My problem is: If I open the product detail and I click add to cart, this is not added and the cart remains empty.
Can you tell me what can be the reason?

I don't see prices, without any prices you can't order items.

Prices are there but they are not visible. If I open a category and once I click add to cart works. Only products in detail does not work.

I tried to visualize prices and works. Thank You.
Although in my opinion is a feature abnormal.

I don't think it is abnormal, as in the cart there where also no prices present.
