hello, i want to show count of only configurable products of current category on category page. for that I have written following code...

<?php $cate = Mage::registry('current_category')->getName();

                $total=0;


               $category = Mage::registry('current_category');

               $products = $category->getProductCollection();

              foreach ( $products as $_product )
                 if ($_product->isConfigurable())
                 {
                    $total++;
                 }
                 echo $cate."(".$total.")"; ?>

my problem is the code is showing the total count of configurable products of all child categories... can anyone help me with this?
