upload progress returning null
<p>I know this me be close little or no info but Im trying to get my uploader to work and im only posting this code because it is the one giving me the problem, I have 2 other files if I need to show those if needed, however this is the problem. When I try to upload a file and the progress bar is suppose to work I keep getting a null error and im not sure why.</p>

<pre><code>&lt;?php

header('Expires: Tue, 08 Oct 1991 00:00:00 GMT');
header('Cache-Control: no-cache, must-revalidate');

if(function_exists("uploadprogress_get_info")){
    $info=json_encode(uploadprogress_get_info($_GET["id"]));
    //echo $info;
    //exit();
}
else
    $info="uploadprogress not installed";

echo $info;
?&gt;
</code></pre>
