Guestbook : parse error, unexpected $

Hi friends

Excuse me, my English is not so good!

I've worked for more than 2 years with the advanced guestbook.
Today I tried to install the newest version (2.3.1) on a new URL.

I didn't have any problems with unzip, upload, create tables
and set the rights 777. I can see the indexsite. But when I
would make an entry and klick on the button "sign the guestbook"
get the following errormessage.

Parse error: parse error, unexpected $ in /home/.sites/117/site84/web/guestbook/lib/add.class.php on line 354

Do you have experience with this error? Could you give me a hint??

I'm looking forward to receiving your answer.

Thanks a lot for your help!!!
