Low stock notification when add to cart frontend users

[MarinDJ]

Hi, this is my first post and tryed to find soultion here but not so need help.

I need option for buyers when they add to cart some product let's say quantity of 5 product in cart and in stock we have only 3 pcs of that that product to show them in popup fancybox or else to show them message like "max quantity for this product is 3".
My setting in Vm > configuration > shopfront > Action when a Product is Out of Stock - Send low stock notification  & Displays 'Notify Me' instead of 'Add To Cart' button

Is it possible?

I have VirtueMart 3.0.12 and Joomla 3.4.8

Thanks!
