What does this mean in the guestbook readme...

2.Upload guestbook.pl in ASCII-mode to your cgi-bin directory
and change mode it to 755 (-rwxr-xr-x).

I am so new to this its not even funny and I cannot get this thing to work on my site using DreamWeaver and I have a site at Geocities... pro, not free... How do I install the basic guestbook, not the advanced. Any help would be hot savvy thx

I also do not understand number 1 either...

1.Open guestbook.pl with a text editor.
Change the url in line one, to the Perl program at your server.
Usually it is: - /usr/bin/perl or /usr/local/bin/perl for Unix.
- C:/Perl/Perl.exe for Windows (use slash "/")
Set the correct paths and required urls.

I have a cgi-bin i made... all i did was create a file named cgi-bin... I put everything where the ZIP file unzipped them to my website folder on my computer. Put some files into /book and some files into /cgi-bin

Now, what do I do to get this thing working using DreamWeaver and uploading everything to geocities. If anyone can help me i would be so thankful. My MSN is SlntNinja@hotmail.com my AIM is MixinUpLife if you would like to talk to me live over that. I would really appreciate it.
