What am I doing wrong?

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

<html>

<head>
<meta name="GENERATOR" content="Microsoft FrontPage 6.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Monthly Poll</title>
</head>

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

</body>

</html>

and what is your error ?

i think, the path could be a problem /...../poll/poll_cookie.php

As MeisterGigi said, probably a path issue looking at the code you posted.

Can you post the actual error message or provide a link to the page the poll is on?
