HELLO~! I am reasonably new to Perl and need some help to write a TELNET script to logon to Cisco router and then output the session to a text file.
At the moment my script reads an excel file for the logon details and it then begin to telnet to the MULTIPLE cisco routers. I want the script to telnet to the router, run commands, and then output the telnet session screen to a separate text file.
My script is screwed somehow and I am pulling my hair out! HELP Please.
1)After the first telnet session router it doesn't output any further sessions.
2)ALSO if a telnet session fails it doesn't skip that one and move on. It just end the script. 

#!/usr/bin/perl
require Net::Cisco;
use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft Excel';

my $routerip;        # router ip address
my $routerun;          #logon username
my $routerlgnpwd;      #logon password
my $routerenpwd;        #enable password

$Win32::OLE::Warn = 3;    # die on errors...
# get already active Excel application or open new
my $Excel = Win32::OLE->GetActiveObject('Excel.Application')
    || Win32::OLE->new('Excel.Application', 'Quit');
# open Excel file
my $Book = $Excel->Workbooks->Open("c:/SCRIPTS/data.xlsx");
# select worksheet number 1 (you can also select a worksheet by name)
my $Sheet = $Book->Worksheets(1);
#Read the excel spread sheet for logon details
foreach my $row (1..2){  #ROWS    This is for a spread sheet with 2 ro
+ws and 4 columns
           foreach my $col (1..4){ #read row column by column
                   use Switch;
            switch ($col) { #set values for telnet logon for excel row
        case 1    {$routerip =$Sheet->Cells($row,$col)->{'Value'}}
        case 2    {$routerun =$Sheet->Cells($row,$col)->{'Value'}}
        case 3    {$routerlgnpwd =$Sheet->Cells($row,$col)->{'Value'}}
            case 4  {$routerenpwd = $Sheet->Cells($row,$col)->{'Value'
+}}
            }#//switch
          # skip empty cells
          next unless defined $Sheet->Cells($row,$col)->{'Value'};

         # print out the contents of a cell
         # printf "%s  ",
           $Sheet->Cells($row,$col)->{'Value'},
           $Sheet->Cells($row,$col)->{'Formula'};
     }#// For Column

      print ("\nAbout to telnet to Router:\nIP: $routerip using:\nUN: 
+$routerun \nPW: $routerenpwd \nEN: $routerlgnpwd \n");
        #  Log on to Router and perform commands output label the rout
+er ip.
    my $session = Net::Telnet::Cisco->new(Host => $routerip , Input_lo
+g =>"c:/SCRIPTS/$routerip.log");
    $session->login($routerun, $routerpwd);
    if ($session->enable($en)){                 #'cpx270zby9'
            @output = $session->cmd('show run | include username');
            print ("Finished $routerip Router Command \n");
        } else {
        warn `Can’t enable:`. $session -> errmsg;
        }
    $session -> close;
}#//For Row
$Book->Close;  # close excel doc
