Problems with guestbook

I don't know WHAT to fill in in the line :# base directory to all guestbook files from the server root without trailing "/" >>$base_dir = "/home/usr/you/book";
This line i've got to fill in the guestbook.pl

Anyone who can help me please ?

This depends on your server os.
On Windows paths starts with 'drive letter'
e.g.
c:\\programs\\wwwroot\\cgi-bin\guestbook.pl

on unix paths starts with '/'
e.g.
/var/www/html/htdocs/cgi-bin/guestbook.pl

If you are not sure, ask your server admin

Thank very much .This helped me out !!!!
