'populate' is undefined

I get this error, but i've traced endlessly and can't find a solution.. Can anyone please help me out?

Here's the script of the slideshow.php:

-----------------------------------------------------------------------------
<?php
$templates_used = 'slideshow';
$main_template = 'slideshow';

define('GET_CACHES', 1);
define('ROOT_PATH', './');

include(ROOT_PATH.'global.php');
require(ROOT_PATH.'includes/sessions.php');
$user_access = get_permission();
include(ROOT_PATH.'includes/page_header.php');

if (!$cat_id || !isset($cat_cache[$cat_id]) || !check_permission("auth_viewcat", $cat_id)) {
header("Location: ".$site_sess->url(ROOT_PATH."index.php", "&"));
exit;
}

if ($action == "slideshow") {

$txt_clickstream = "";
if ($cat_id && isset($cat_cache[$cat_id])) {
$txt_clickstream .= get_category_path($cat_id, 1).$config['category_separator'];
}
}

$slideshow_id = $cat_id;
$slideshow_id = MEDIA_DIR."/".$slideshow_id."/";
$main_template = 'slideshow';
$file_array = "";
$random_cat_image = (defined("SHOW_RANDOM_IMAGE") && SHOW_RANDOM_IMAGE == 0) ? "" : get_random_image($cat_id);

$countit = 0;
$file_array = "theimage[0]=[' ','";
$mydir = opendir($slideshow_id) ;
$exclude = array("mp3","php","gif") ;
while($fn = readdir($mydir))
{
if (stristr($fn,$exclude[0]) ||stristr($fn,$exclude[1]) ||stristr($fn,$exclude[2]) || strlen($fn)< 3 ) continue;
$countit = $countit + 1;
$file_array = $file_array."".$slideshow_id."".$fn. "',' ']; theimage[".$countit."]=[' ','";
}

closedir($mydir);

$file_array = substr("$file_array", 0, -19);
if ($countit == 0) {
$msg = "There are no images available for the slideshow. Please try another category";
}

//echo "$file_array";

$clickstream = "<span class=\"clickstream\"><a href=\"".$site_sess->url(ROOT_PATH."index.php")."\" class=\"clickstream\">".$lang['home']."</a>".$config['category_separator'].$txt_clickstream."</span>";

Looks like you've been shunted around the forums on this one. The problem is in your JavaScript. View the source of the page your PHP generates and post that to the JavaScript forum - you might get more replies then.
Good luck

BTW this has nothing at all to do with Java (Java and JavaScript are very different)
