poll_process(4); ?> Appears instead of poll

<?php
include_once "/xxx/poll/booth.php";
echo $php_poll->poll_process(4);
?>

I pasted that into my webpage but it comes out like this:
poll_process(4); ?>

How do I keep it from doing that???

never mind... stupid me forgot to rename something :/

<?php
include_once "/xxx/poll/booth.php";
echo $php_poll->poll_process(4);
?>

I pasted that into my webpage but it comes out like this:
poll_process(4); ?>
