ok, here is what you do
1) Create a page called Category test
when you publish the page, make note of the address in your browser window. It will be something like
HTML Code:
http://yourdomain.com/wp-admin/page.php?action=edit&post=248
Write down the number at the end, in tis case '248' that is the page number and don't worry if you only have 3 pages, a page is really a special type of post so the numbering is not sequential.
2) go to ATO->Style & edit CENTER COLUMN->The LOOP and find the line
HTML Code:
<?php bfa_post_bodycopy('<div class="post-bodycopy clearfix">','</div>'); ?>
insert the following right after that line
HTML Code:
<?php if (is_page(248)) {wp_cat_posts(4); } ?>
So now, when ever you are displaying page 248, it will list all the items in category '4' on the page.
Hope this helps
