Cannot sign guestbook 1.5

Hi
When I want to sign the book I get the following message;

Guestbook - Error
Cannot find sample file template.html in /home/bdweb7181j/nadinemcneil.com/public_html/book

I cannot recall what this template is the book is talking about.
The url is:
http://www.nadinemcneil.com/book/addentry.html

Could anyone please explain what they mean with this template.html??

Thanks
Dineke

template.html is a file that is supposed to be in your book directory. Maybe it got accidentally erased or corrupted? You should upload it again to your server.

Hi
if i make a copy of guestbook.html and name it template.html would that work?
Thanks again
