Haven't a clue why you would include the script, unless it was to show that you hadn't turned off smilies.

The most common fault is that you didn't check to see if you changed the permissions (chmod) of the cgi-bin to 755.

You should also make sure that you uploaded the script to cgi-bin directory on your server and modify URL in the Script field in the Proxy Analyzer General Settings.

You may also have problem with "#!/usr/bin/perl" string (first string of the script), on some servers this may be "#!/usr/local/bin/perl"; if the script does not work, try to change it.
