Guestbook v1.5 install problem fixed!

For those of you getting this error when installing guest book 1.5:

Guestbook - Error
Cannot create ID file guest_id.txt in /web/book. Please check your base directory.

Just below this message look for the field that says:
DOCUMENT_ROOT
This is the base directory you are needing to put in guestbook.pl file!
at the end of that DOCUMENT_ROOT field entry add the directory where your book files are. Here is what my document root was that got my guestbook working:
/nfs/cust/4/23/35/53324/web/book
If you are running your own server, then you should already know what the document root is, but if you are like me and run your website off of a hosting service like Hostsave.com then this is how you get it to work.

Hope this helps everyone that was just as CLUELESS as I was!

I know I'm replying to a 9 month old post but I just downloaded the guestbook (not advanced) and was having problems finding the correct base directory. This was the first post that actually gave me a clear enough path to follow to figure out the base directory and get my guestbook working, so I figured a little bump for anyone who's been having the same problems...

Your posting helped me get further, but now I'm getting the following message:

The directory /usr/local/apache/vhosts/www.domain.com/guestbook requires mode 777!

The thing is I do have that mode enabled, but still nothing
