advance poll 2.02 embeded

Hi there.
I don't know if you can give me a hand.

I just installed the My SQL advance poll 2.02 and everything seems to be working fine, I even created new polls, the only problem is that I don't know how to embed the poll into my webpage.

------- I followed the instruction, I inserted the codes
<?php
// Important! You have to include it before your html code
include_once "/home/mypage/pollphp/db/poll_cookie.php";
?>

<html>
<body>
<?php
include_once "/home/mypage/pollphp/db/booth.php";
echo $php_poll->poll_process(4);
?>
</body>
</html>

------- but when I save the webpage all it shows is
poll_process(4); ?>

thanks for your help.

Change the pages extension to .php
Also do you have the correct path information to booth.php found under the help section from the main menu?
