Top Downloads Not Writing To Logs

Hi
New to this board and have a problem.

Followed install instructions and uploaded script and .txt files and chmoded as per instructions.
I am able to log into admin and the scan function works fine.

When I click on a download, the count in log.txt stays at zero, although all the downloads from the scan function appear in the log. The daylog.txt and download_stats.txt are both blank.

Can any please tell me why the script wont write a count to the log but the admin part does.

Here is what I have edited. I have tried renaming script to .cgi but it does the same thing as .pl

# url to script
$cgiurl = "http://www.mysite/cgi-bin/dlcount/download.cgi";

# url to the image files without trailing "/"
$base_gif = "http://www.mysite/images/gif";

# administration password - should not contain '&','=' and "
$admin_pass = "********";

# file locking ($lock=0 for Win32!);
$lock = 1;

# check http referer 0=no 1=yes;
$check = 0;
@valid=('http://www.mysite);

# log files
$basedat = "/home/myuser/public_html/cgi-bin/dlcount/log.txt";
$daylog = "/home/myuser/public_html/cgi-bin/dlcount/daylog.txt";
$stats = "/home/myuser/public_html/cgi-bin/dlcount/download_stats.txt";

# base url to the downloads without trailing "/" (use for scanning)
$base_url = "http://www.mysite/files";

# path to the downloads from the server root! (use for scanning)
$base_dir = "/home/myuser/public_html/files";

$back_img = "http://www.mysite/images/gif"; # url of background image

Have you set all the file permissions correctly?
Are there any errors being displayed?

All file permissions are set properly. .cgi(.pl) to 755 and .txt to 666
No errors are displayed.

What is strange is that after doing a scan in admin, the files found are written to the log.txt but when clicking a download from the site, it doesn't write it to the log, although it does download properly.

ie: The count always stays at zero.
