.htaccess problem

I have the following .htaccess file:

<Files about>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files contact>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files management>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files success>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files><Files about>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files contact>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files management>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>
<Files success>
    AcceptPathInfo on
    SetOutputFilter PHP
    SetInputFilter PHP
</Files>

Code (markup):

As I try to open pages like about however, the web server (Apache2) does not process this file as a php file. I presume that I am not configuring Apache2 correctly, but I don't know how, where or what. How can I make this work? What am I doing wrong???

I'd appreciate any help on this.

 

Why do you have this in you .htaccess file?
