When you are adding a catagory what are you suposed to put in the header foot section?

These fields allow you to add different headers and footers to your categories. If you want to insert specific content to your Apples category, create apples.txt, upload it to the folder you specified in links.cfg and - in case it's a footer - call it as follows in category.html:

<%if footer%>
<%footer%>
<%endif%>

Header and footer paths are already set in links.def:

$db_header_path = $db_script_path . "/header";
$db_footer_path = $db_script_path . "/footer";
