script email function not working

In another thread I have been fine tuning a bad bot script and my .htaccess file. I have one final problem to sort out.

The email the script sends is not delivering the IP address of the intruding bot. My error logs give the following - which seems to indicate the problem:

PHP Notice: Undefined variable: bot_ip in /var/www/vhosts/mydomain/httpdocs/trap/get_lost.php on line 33

line 33 of the script reads:
msg = "address is " . $bot_ip . "\nagent is " . $_SERVER['HTTP_USER_AGENT'] . "\n";

the resulting bad bot email reads: (there is a blank after "address is" instead of the IP)
************************************
A bad bot hit /WebCalendar/any.file

agent is Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.8.1.7)
Gecko/20070914 Firefox/2.0.0.7
*************************************

the get_lost script is here: the "$bot_ip" string seems to work when applied to writing to .htaccess but doesn't seem to return a result when writing the email

$msg = wordwrap($msg, 70);
mail($to, $subject, $msg, "From: $from");
}

function block_bot($t, $f){
$fh = fopen($f, 'ab');// open in binary mode just in case
fwrite($fh, $t);
fclose($fh);
}

$bot_ip = userIP();
// block the bot
$txt = "deny from $bot_ip\n";
$file = '/var/www/vhosts/mydomain/httpdocs/.htaccess'; //edit for path to your htaccess file
block_bot($txt, $file);
tel_me();

Many thanks.
