Sorry,
The following code will only show a particular tab in one category.
Code:
{if $product.categoryid == 18}[*]
Guarantee{/if}
In the cart I am currently working on I have a category with several subcategories that I need a particular tab to only show in.
So I need this tab to show in cat id 19, 20, and 21.
Hope this clears things up???
