Would appreciate help on Guestbook 1.51

Hello,

I get an errormessage on Guestbook 1.5 when im trying to set it up. My problem are that I can't understand what I am doing wrong.

The errormessage says :

Guestbook - error
The directory /home/sam-design/mainwebsite_html/kjetil requires 777!

Has changed it to 777 ... but I still get the error message. Guess that the problem are that it can't open guest_id.txt, but i am empty on ideas for what can be wrong now

Please, help me out here if possible. And yes, i am a newbie on this ... so a LOL is ok if this is a stupid question

I have the same error.
What the solution ????
thks,

Hey all you have to do is change permissions to that directory to 777 thats all it wants
