Hi. %hash is not a a hash reference, is a hash. Check the following:

# This is a hash:
my %hash = (     1 => 'one',
        2 => 'two',
    );

# This is a hash ref:
my $hashref = {    1 => 'one',
        2 => 'two',
    };

# This is a hash ref of the hash above:
my $hashref2 = \%hash;

# Get a hash value:
print "Hash: " . $hash{1} . "\n";

# Get a hashref value:
print "Hash ref: " . $hashref->{1} . "\n";

Edited: Also just noted that the values of your hash are array references, so the print line should be:

print $_, "\t", $hash{$_}->[1], "\t", $hash{$_}->[2], "\n";
