I would like to do this too...
Not working for me..I have this at the head of the subcategories.tpl
{if $cat=251}
<a href="product.php?productid=16134&cat=251&page=1">
{else}
<a href="home.php?cat={ $subcategories[cat_num].categoryid }">
{/if}
My category # is 251 and product # is 16134.
Any thoughts?
Thanks
