Showing product quantity at featured post

Hi,

I’d like to show quantity in featured_product overwiew, but I’m not able to get it (see http://cenovymaniak.cz – if you click on product, you’ll see there but not at main page)

I’ve added following code:

<div style="margin-top:21px;margin-right:22px;border:1px solid #25ACD7;float:left;display:inline">
  <div style="float:left;padding:2px;">
    zbývá
  </div>
  <div style="background-color:#25ACD7;padding:2px;color:white;float:left;">
    <?php echo $product['quantity'] ?>ks
  </div>
</div>

What is wrong? Everything like $product[‘title’]; is working but not quantity…? Thanks for your help (by the way, great product! guys)
