Why doesn't the cgi perl method call?

Hello.

Outputs:

Software error:
Can't call method "f" on an undefined value at /var/www/html/cgi-bin/install.cgi line 12.


Line 12:

my $f = $ses->f;

Clearer:

#!/usr/bin/perl
use strict;
use lib '.';
use XFileConfig;
use Session;
use CGI::Carp qw(fatalsToBrowser);
require DBI;

my $ok = "<br><b style='background:#1a1;color:#fff;padding:2px;'>OK</b>";

my $ses = Session->new;
my $f = $ses->f;

I tried to use this instead of Session: CGI::Session

Also, I changed where it swears at this:

my $ses = CGI::Session->new();
my $f = $ses->id();

There were other errors.
How to decide?
