Perl Monks, I am trying to use user input for username and password. Then run password to change the current password. I seem to having issues passing the input the first time. If I put the username and password in the script it works but soon as I put the variables I get the error on line 34. Here is my code and here are the errors as well. Thank you in advance.

#!/usr/bin/perl

use strict;
use warnings;
use Net::SSH::Expect;

print "Enter your username: ";
my $unme =<>;
print "Enter current passwd: ";
system('stty','-echo');
chop(my $cur_pswd =<STDIN>);
system('stty','echo');
print "\n", "Enter new passwd: ";
system('stty','-echo');
chop(my $new_pswd =<STDIN>);
system('stty','echo');
print "\n", "Enter new passwd again: ";
system('stty','-echo');
chop(my $val_pswd =<STDIN>);
system('stty','echo');
print"\n";
if ($new_pswd eq $val_pswd){
my $ssh = Net::SSH::Expect->new(
    host  => 'localhost',
    user  => "$unme",
    password => "$cur_pswd",
    raw_pty => 1
);

warn "Starting SSH... \n";
$ssh->run_ssh();

warn "Testing login output... \n";
my $login_output = $ssh->login(); 
print " Done", "\n";

my $who = $ssh->exec('who');
print($who);

} else{
        print "wrong password ! \n";
}
