anjultyagi:

You're creating the hash value just fine. It's just that when you pass a hash to a function, it's expanding into a list. So when Dumper runs, it's dumping each value in the list separately, so it doesn't look like what you're expecting. Here's an example:

$ cat u.pl
use strict;
use warnings;
use Data::Dumper;

my $hashRef = {amountSubmitted=>1};
print "a hash reference: ", Dumper($hashRef), "\n";

my %hash = (amountSubmitted=>0);
print "a hash expands to a list: ", Dumper(%hash), "\n";

print "pass the hash as a ref: ", Dumper(\%hash), "\n";

When run, it'll look like this:

$ perl u.pl
a hash reference: $VAR1 = {
          'amountSubmitted' => 1
        };

a hash expands to a list: $VAR1 = 'amountSubmitted';
$VAR2 = 0;

pass the hash as a ref: $VAR1 = {
          'amountSubmitted' => 0
        };

So when you're going to use Dumper to display a hash, be sure to use a hash reference instead of letting the hash expand to a list of values.

You should be aware that the same thing happens with arrays: If you use Dumper on an array, you'll get $VAR=first array value, $VAR=second array value, etc., unless you use an array reference:

$ perl u.pl
array reference: $VAR1 = [
          'first value',
          'second value'
        ];

array: $VAR1 = 'first value';
$VAR2 = 'second value';

array as ref: $VAR1 = [
          'first value',
          'second value'
        ];

Update: Added bit about array/arrayref.
