Hi Experts,

I am new to perl hash references, i am trying to print the out put but i am getting errors

#!/usr/bin/env perl -l
use strict;
use warnings;
use Inline::Files;

my @file_handles = \(*file1, *fil2, *file3);
my %data;

for my $fh (@file_handles) {
    while (<$fh>) {
        $data{in}{$type}{$id}{val1} += $val1;
        $data{in}{$type}{$id}{val2} += $val2;
        $data{in}{$type}{$id}{val3} += $val3;
        $data{in}{$type}{$id}{val4} += $val4;
        $data{subtotal}{$type}{val1} += $val1; 
        $data{subtotal}{$type}{val2} += $val2; 
        $data{subtotal}{$type}{val3} += $val3; 
        $data{subtotal}{$type}{val4} += $val4; 
        $data{total}{val1} += $val1; 
        $data{total}{val2} += $val2;
        $data{total}{val3} += $val3; 
        $data{total}{val4} += $val4;
    }
}

close FILE;

for my $type (sort keys %{$data{in}}) {
    print "$type\n";
    for (sort keys %{$data{in}{$type}}) {
        print join("\t" => $_, @{$data{in}{$type}{$_}}{qw{val1 val2 va
+l3 val4}})."\n";
    }
    print join("\t" => 'Sub', @{$data{subtotal}{$type}}{qw{val1 val2 v
+al3 val4}})."\n";
}
print join("\t" => 'Tot', @{$data{total}}{qw{val1 val2 val3 val4}})."\
+n";

Tot1 should sum the value of sub for CACK,KACK and RACK and Tot should sum the values of all subs

please guide me on this,thanks in advance
