Thanks for your reply. I am trying disable it altogether by locking the table. Spammers posts 20/30 entries in my guestbook.

If you 'lock' the table then nobody will be able to post to it, neither spammers nor rational humans. If you don't want anyone posting to it, just disable the form that is used to submit posts ... form action="#" would do that.

If what you want is something to allow guests and slow down idiots, then you might want a 'captcha' - one of those security image things that people can read and bots can't to ensure posts are made by people.

Thanks for your reply. I found a script how to prevent span in [a href=\"http://php.webmaster-kit.com/\" target=\"_blank\"]http://php.webmaster-kit.com/[/a]
In order to add a comment in my guestbook go to [a href=\"http://www.regobarros.eng.br/guestbook/livro.php?a=add\" target=\"_blank\"]http://www.regobarros.eng.br/guestbook/livro.php?a=add[/a]
But I have a problem visitor entered correct number or wrong number.
[code]In action script you can use following code:

include "audit.php";

if (audit()) {
      // Visitor entered correct number
} else {
      // Wrong number
}

The function audit() returns "true" if the number entered by the visitor coincides with the number on the image, and returns “false” in other cases. [/code]
I do not know where I put this code. Part my script is:
[code]function add() {
    global $PHP_SELF;
    print("
    <center>
    <form action=\"$PHP_SELF\" method=\"post\">
