category description on main page only

[Academy]

if we have many products under one cateogry, the category's description will display at all sub-pages, how to let category description on main page only?

[Acequia]

/common_files/customer/main/subcategories.tpl

{if $smarty.get.page lt 2}
  {if $current_category.description ne ""}
    <div class="subcategory-descr">{$current_category.description|amp}</div>
  {/if}
{/if}

wrap those if tags around the description and see what happens. for me it is near line 20.
This should get the page number from the url, if it is higher than 1 the description should not be displayed.
