GUEST BOOK ERROR

IN MY SITE THIS GUEST BOOK IS NOT WORKING,ALL THE USERS GETTING THE ERROR Like

Guestbook - Error
One of the input fields does not seem to be valid.

BUT IAM I SURE ALL DATA ENTERED IN INPUT FIELDS ARE VALID

IS THERE ANY FIX

A link would be nice.

HEY NOTHING IS THERE WHAT IS THIS

I THINK link is here http://www.grainsandpixels.com/guestbook/addentry.php

SORRY I THINK IN UR REPLY UR TRYING TO POST THE LINK OF UR HOME PAGE.I CANN't FIND ANY RELATED TO THIS ERROR IS THERE, SO I REPLY.
SORRY ONCE AGAIN, THANKS FOR UR QUICK REPLY

I would say the problem lies in the fact that all the inputs have been renamed. For example you have name="name" when it should be name="gb_name".

SORRY IAM NOT A PHP EXPERT,SO PLEASE SPECIFY IN THAT BELOW LINE WHERE I WANT TO MODIFY name

$gb_post->name = (isset($HTTP_POST_VARS["name"])) ? $HTTP_POST_VARS["name"] : '';

Did you download the guestbook from here or did your host provide it? It may be worth you downloading it from here again and overwriting your existing version, or upload it to a different directory first to test it.

MY HOSTING PROVIDER IS PROVIDING THIS GUEST BOOK,IF I CREATE A NEW GBOOK THEN MY OLD DATABASE WILL ERASE,IWANT TO PRESERVE THEM.

I said reupload the files I did not say reinstall the guestbook. You can download the guestbook from here, extract all files to a folder called gbook2 and then fill in the admin/config.inc.php file. Upload the gbook2 folder to your website and then see if it works properly. DO NOT RUN THE INSTALL.PHP FILE.

sorry again , I replaced all files,but getting same error,

Guestbook - Error
One of the input fields does not seem to be valid.

I'll lok into what calls that error when I get home, if possible would it also be possible to have ftp access to your server so I can check the files on your space.

PLEASE HELP CARBONIZE I AM NOT ABLE TO REMEMBER MY MYSQL PASSWORD, IWANT TO INSTALL MY GUEST ,BUT IF IT POSSSIBLE

MY EXISTING DATA BASE.

your hosts will be able to provide you with your MySQL password. Odds are it is available in your Control panel.

IT IS THERE BUT IT IS IN ENCRYPTED FORMAT ,BECAUSE THIS SCRIPT WAS INSTALLED BY FANTASTICO!!!!!
