Sorry I am trying to paste in what data::dumper prints out to show you what this hash of hashes looks like but when I use the code tags / its just not displaying correctly

    From this: 

    
$VAR2 = 
    { 'dev' => 
            [ { 'nfsmount' => { 'bigstor_nfs' => { 'bigstor17_mpt' => 
                { 
                  'filer_device' => 
                     { 
                        'ny_loc' => 'nnap5307-s', 
                        'nj_loc' => 'nydevnfs_bigstor_volC' 
                     }, 
                        'filer_volume' => 
                            { 
                                'ny_loc' => '/vol/bigstor_volC/bigstor
+17', 
                                'nj_loc' => '/vol/bigstor_volC/bigstor
+17' 
                            },

    To access 'nydevnfs_bigstor_volC' you would do: 

    $VAR2->{dev}[0]{nfsmoun}{bigstor_nfs}{bigstor17_mpt}{filer_device}{nj_
+loc}

    You can use the iteration logic provided below along with this to reach any element you need.

    That's because you omitted the closing code tag, </code>. Pls fix.
