problem with global stock in product-list

[phil3001]

Good evening,

in my site I dress size S which is always set by default.

in product-list, if the size S is exhausted but if I still have a total of 10 articles, for example, this means exhausted.

How do I get the message starts based on the global stock and non stock in the default size.

I found the line to edit but I do not know the proxy

{if ($product.allow_oosp OR $product.quantity > 0)}{l s='Available'}{else}{l s='Out of stock'}{/if}
