Dont allow users to add more quantity than avaiable

[amorxoigel]

Hey guys!
as the title say i would like to not allow users to add in the cart more quantity of a product than avaible quantity (in the product page).
I mean it would be good that user could be able to increase the quantity number just till the maximum avaible but without exceed it.
any idea on what should i change? I guess i need to change something in this file "product-add-to-cart.tpl" but idk what to do,

Thanks in advance
