PROBLEM Whit Access Stats!!

My problem is that when i go to the page where my stats should be, there isnt any stats at all... It just reads "Access Stats 1.12" and "Logfile". Im not sure have i put all url`s and path`s right in stat.pl and log.pl. What exactly i shoul put here?:

# path to the log files from the server root without trailing "/" (chmoded to 777 (drwxrwxrwx))
$base_dir = "../logfiles";

Help me please, i have tryed to fix this for 4hours!!!
