Hi capriguy84,

Looks to me like you've got a simple typo ... first you called the data structure %HOH, then later you referred to it as %HoH. One other typo in your code is the extra quotation mark (or "double quotes" character) on this line:

pal => "[ "george", "jane", "elroy" ],

Fixing those 2 things, giving explicit values for $key and $value, and using Data::Dumper to check the results:

use strict; use warnings; use Data::Dumper; my %HoH = ( flintstones => { lead => "fred", pal => [ "george", "jane", "elroy" ], }, jetsons => { lead => "george", wife => [ "george", "jane", "elroy" ], boy => [ "george", "jane", "elroy" ], }, simpsons => { lead => "homer", wife => [ "george", "jane", "elroy" ], kid => [ "george", "jane", "elroy" ], }, ); my $key = 'flintstones'; my $value = 'Wilma'; printf "Before: %s\n", Dumper(\%HoH); $HoH{$key}{"name"} = $value; printf " After: %s\n", Dumper(\%HoH); __END__ Output (Note that 'Wilma' was successfully added): Before: $VAR1 = { 'simpsons' => { 'kid' => [ 'george', 'jane', 'elroy' ], 'lead' => 'homer', 'wife' => [ 'george', 'jane', 'elroy' ] }, 'jetsons' => { 'lead' => 'george', 'wife' => [ 'george', 'jane', 'elroy' ], 'boy' => [ 'george', 'jane', 'elroy' ] }, 'flintstones' => { 'lead' => 'fred', 'pal' => [ 'george', 'jane', 'elroy' ] } }; After: $VAR1 = { 'simpsons' => { 'kid' => [ 'george', 'jane', 'elroy' ], 'lead' => 'homer', 'wife' => [ 'george', 'jane', 'elroy' ] }, 'jetsons' => { 'lead' => 'george', 'wife' => [ 'george', 'jane', 'elroy' ], 'boy' => [ 'george', 'jane', 'elroy' ] }, 'flintstones' => { 'lead' => 'fred', 'name' => 'Wilma', 'pal' => [ 'george', 'jane', 'elroy' ] } };

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 How to display code and escape characters are good places to start.
