Hi Serf, I was trying to add another column which is the last month period in the report output. I was able to get the last month period like 1 Feb 10 - 28 Feb 10. But when I tried to add the column in the program. The new "Period" column is inserted in a diffent row.

Current Ouput with new Period Column:

CUSTOMER NAME: AGD-WEb
Period Device_Code Port Traf_Dir Data_Usage
1Feb2010 - 28Feb2010
SWITCH Fa1_0_33 OUT1.311
1Feb2010 - 28Feb2010
SWITCH Fa1_0_33 IN10.716
1Feb2010 - 28Feb2010
SWITCH Fa1_0_35 OUT50.796
1Feb2010 - 28Feb2010
SWITCH Fa1_0_35 IN7.882
1Feb2010 - 28Feb2010
SWITCH Fa2_0_33 OUT-0.000
1Feb2010 - 28Feb2010
SWITCH Fa2_0_33 IN-0.000
1Feb2010 - 28Feb2010
SWITCH Fa2_0_35 OUT-0.000
1Feb2010 - 28Feb2010
SWITCH Fa2_0_35 IN-0.000

Here's the code I updated with $lastmonth_period (I use DateTime module from CPAN) :) : 
for my $customer ( keys %$cust ) {

    # If you want to write to a file named with the customer ID
    # my $output = "./$customer.out";

    # If you want to write to a file named with the customer name
    my $output = "./$cust->{$customer}->{name}.txt";
    open (CUST_OUT, ">$output") || die "Can't write to '$output': $!\n
+";
    
    print CUST_OUT "Data Transfer Report for $cust->{$customer}->{name
+}\n" .
        "Period                         Device_Code      Port        T
+raf_Dir Data_Usage\n";

    for my $device ( sort by_name keys %{$bill_data->{$customer}} ) {

        for my $port ( sort keys %{$bill_data->{$customer}->{$device}}
+ ) {

            (my $short_port = $port) =~ s/^FastEthernet/Fa/g;

            for my $direction qw(OUT IN) {
                print CUST_OUT "$lastmonth_period $device $short_port 
+$direction"  .
                    $bill_data ->{$customer}->{$device}->{$port}->{$di
+rection} . $/;

     } 
         
      }       

    }

    close(CUST_OUT);

}

The output I am trying to do should be like:

CUSTOMER NAME: AGD-WEb
Period Device_Code Port Traf_Dir Data_Usage
1Feb2010 - 28Feb2010 SWITCH Fa1_0_33 OUT1.311
1Feb2010 - 28Feb2010 SWITCH Fa1_0_33 IN10.716
1Feb2010 - 28Feb2010 SWITCH Fa1_0_35 OUT50.796
1Feb2010 - 28Feb2010 SWITCH Fa1_0_35 IN7.882
1Feb2010 - 28Feb2010 SWITCH Fa2_0_33 OUT-0.000
1Feb2010 - 28Feb2010 SWITCH Fa2_0_33 IN-0.000
1Feb2010 - 28Feb2010 SWITCH Fa2_0_35 OUT-0.000
1Feb2010 - 28Feb2010 SWITCH Fa2_0_35 IN-0.000

Also, I need to get the total Data Usage of each customer, so i need to get the sum. Can please help me on this? Or how should I update the code from here? I'm currently lost right now.
Thanks a lot!
