have you ever tested your code? this is broken!!
however you should look at perldoc perlref on how to build code refs..
this is a working version:

#!/usr/bin/perl -w

use strict;

sub print_me {
  my $arg = shift || "Hello World!\n";
  print $arg;
}

my %hash = (no_arg => sub { &print_me()},
        with_arg => sub {&print_me("Hello again!\n")}
        );

$hash{no_arg}->();
$hash{with_arg}->();

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
