htaccess Elite

Hi,

I have .htaccess files clashing... which is breaking an rss feed function that I use to feed my blog posts into the bottom of my articles, for example: http://theebooksale.com/articles/new-to-internet-marketing-here-are-some-tips.html.

In \rss_installer directory (for blog feeds into article pages), I have the following:
AddType application/x-httpd-php .htm
AddType application/x-httpd-php .html

In the root directory (for rss feeds in my homepage, http://theebooksale.com), I have the following:
AddType application/x-httpd-php .htm .html
AddHandler x-httpd-php .html

The latter is clobbering the former to the extent that the blog feeds are not displaying in the article pages!!! I've tried everything... anyone any ideas?

Thanks.
