Mark,
I have not got good access to change things on my hosted account so here is what I do - not very elegant but works for me.
In your .htaccess file (I place one in the root of my site) add the following lines
To include PHP parsing for .html,.htm etc add the following lines with the list of extensions you want parsed.
AddType application/x-httpd-php .php .php3 .html .htm .phtml .cb .asp
To add support to a specific file, in this case mark add the following 3 lines
<Files mark>
ForceType application/x-httpd-php
</files>
To parse files with no extension (think does all files) add the three lines
<Files *>
ForceType application/x-httpd-php
</Files>
Hope this helps
Bryce
