show/hide add to cart button on product sheet

[marhor.hr]

When examining the product sheet (product.tpl) with firebg, i see a piece of code that shows the add to cart button:

<p id="add_to_cart" class="buttons_bottom_block" style="display: block;">

 

 

<span></span>

 

<input class="exclusive" type="submit" value="U košaricu" name="Submit">

</p>

 

Depending on if the product is in or out of stock, the display style changes dynamicly between display:none and display:block.

I'm rather inexperienced in php and can't find it in the product.tpl file, so can somebody please explain to me how this works?

 

Thanks!

Nobody?

 

Nobody knows or just won't bother explaining?
