Help us out by posting the offending code.
I assume you're doing something like this:
# fetch existing cookies
%cookies = fetch CGI::Cookie;
$id = $cookies{'ID'}->value;
If there is no cookie named 'ID', then $cookies{'ID'} would be
undefined, so $cookies{'ID'}->value would be equivalent to
undef->value;
which is obviously a problem. You really need to make sure you
received a cookie named ID first by something like:
%cookies = fetch CGI::Cookie;
$id = defined($cookies{ID}) && $cookies{ID}->value;
I can't say why you aren't getting the cookie. Make sure everything
is spelled correctly.
