Perhaps you want the sum of all values under a given 'cost key' ('68-4' in this case).
use strict; use warnings; use List::Util qw(sum); my $VAR1 = { '153-1' => { '19-4' => { 'cost' => '6300.00', 'cost2' => '630.00' }, '135-1' => { '68-4' => { 'cost' => '300.00', 'cost2' => '130.00' } }, '1069-9' => {}, '35-1' => { '28-4' => { 'cost' => '30.00', 'cost2' => '10.00' } }, }, }; my $cost_key = '68-4'; foreach my $temp1 (values %$VAR1) { foreach my $temp2 (values %$temp1) { next if !exists $temp2->{$cost_key}; print sum( values(%{$temp2->{$cost_key}})); } }

OUTPUT:

430

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
