Add subcategory name to product_info.php

[Rachael w.]

I would like to append my product name with the subcategory name on the product_info.php page and just cant get it right. I am able to get the category to show, but its the main category, not the subcategory by using this code:

 

<?php echo $tree[$current_category_id]['name'];?> - <?php echo $products_name; ?>

 

Can anyone tell me what needs to be in there in place of the <?php echo $tree[$current_category_id]['name'];?> so the subcategory shows?

 

Thank you in advance for your help.
