Embedding a poll on my site?

I've been working at this for a long time! I installed the Advanced Poll 2.03 and got to the admin section, and even made a pol,

I put this at the VERY top of my HTML document:

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

Then I put this where I wanted the poll to appear:

<?php
include_once "/usr/home/zareba/public_html/poll/booth.php";
echo $php_poll->poll_process(4);
?>

All that appears on the page is "poll_process(4)"

What am I doing wrong?

I put this at the VERY top of my HTML document:

Make it a .php document.
