in reply to Counting how many times item is occurring and adding the total from array help!

Is this doing what you want?

use Modern::Perl; use Data::Dump qw/dump/; my %seen; my %accounts; my $g_total; while (<DATA>) { next if $seen{$_}++; my ( $account_number, $amount ) = ( split /,/ )[ 2, 7 ]; @{ $accounts{$account_number} }[0] += $amount; @{ $accounts{$account_number} }[1]++; $g_total += $amount; } say dump( \%accounts ); say "Grand Total = $g_total"; __DATA__ Joe Smith,12345678,44552,02/11/2011,no email, MA,USA,900.00,updated Joe Smith,12345678,44552,02/11/2011,no email, MA,USA,900.00,updated Joe Smith,12345678,44552,02/11/2011,no email, MA,USA,900.00,updated Cindy Abbot,122233678,01122,08/09/2012,test@tok.com, CA,EUR,-120.00,up +dated Mary Lou,33456678,44552,01/11/2011,no email, MA,USA,400.00,updated SMith Doo,12345678,44592,02/11/2012,test@test.com, MA,USA,100.00,updat +ed Mario Att,00056789,022345,03/10/2010,no email, MA,USA,40.00,outdated Mario Att,00056789,022345,03/10/2010,no email, MA,USA,40.00,outdated Mario Att,00056789,022345,03/10/2010,ok@ok.com, MA,USA,40.00,outdated Maria Smither,12345678,00051,02/11/2011,no email, MA,USA,750.00,outdat +ed Dan Smither,12345678,00051,02/11/2011,no email, MA,USA,250.00,outdated

Output:

{ "00051" => [1000, 2], "01122" => [-120, 1], "022345" => [80, 2], "44552" => [1300, 2], "44592" => [100, 1], } Grand Total = 2360

The hash %accounts hold the accountnumber as key and each value is a reference to an array containing the total for that account and the number of times the accountnumber was found in the data.

    This is what I am tryin to get at the end:

    Account 44552 - ccurring 1 time(s) - Total = 900.00
    Account 00051O - ccurring 2 time(s) - Total = 1,000.00
    Account 01122 - ccurring 2 time(s) - Total = -120.00
    ...

    Grand Total = 1,780.00

    Thanks for helping!
      Easy! replace the last two lines by:
      say "Account $_ - occurring $accounts{$_}->[1] time(s) - Total = $acco +unts{$_}->[0]" for keys %accounts; say "Grand Total = $g_total";
