Please, help me for install advacend poll

I'm sorry for my question but i don't know the php language and i have some problems for install this in my webpage.

I installed Advanced poll in my cpanel with fantastico. It seem all ok.
I created a poll in my admin page and after i copied:

<?php
// Important! You have to include it before your html code
include_once "/home/wwwscjau/public_html/poll_cookie.php";
?>

before my html code
after i copied:

<?php
include_once "/home/wwwscjau/public_html/booth.php";
echo $php_poll->poll_process(6);
?>

in my page but, when i open my webpage i see only these caracther:

poll_process(4); ?>

Why?

I controlled all in my control panel and the directory of php files is ok.

Can you help me?

Thank's for help and sorry for my bad english,

just rename your .html page to .php
