Somebody can help me with Advanced Poll?

Hi..

I already had the Advanced Poll in my server when he was php 4.2.3 functioned normally.

Now they had changed the version of php for 4.3.0 and appears the following error:

Fatal error: Cannot redeclare set_max_bar_length() in /home/myserver/poll/include/class_poll.php on line 116

This happens when I make the include in the page
example: in my index.php.. i use

<?php
require "/home/myserver/poll/booth.php";
$php_poll->set_template_set("popup");
echo $php_poll->poll_process("newest");
?>

Somebody knows why is happening this error?

Please!!.. help me!!

Thanks!!
