Quantity Button UP/DOWN

[gabri_game]

Hi, I am using Joomla 3.4.0 and I update virtuemart to 3.0.6.2 and I have an error that I can't solve. I have a problem with the button near "add to cart" in the category and product view. If I update the nº of the product with the button, the number "1" (default) disappears to "NaN" and appear a message sometimes that say something as"this product only can be shopped in 1 unit", but if put "2" manually or in the cart add the nº of item, it works.

I search and I don't find solution for this version, how I can solve it ? 

I thing that my template override something (it was works fine until the update) and with the last version the code has changed, but I don't find the file that contains this code in virtuemart.

Thanks for all.
