You're pretty close. I think you just forgot a necessary "@" sigil in the assignment to @value. Try it like this:

@value = @{$hoh{$newcount}{'individual'}};

Here's a little one-liner cook-book example to demonstrate the concept:

perl -MData::Dumper -e '%h=(one=>{a=>[1,2,3],b=>[4,5,6]},two=>{b=>[5,6
+,7],c=>[7,8,9]});
 print Dumper(\%h); @a=@{$h{one}{a}}; print Dumper(\@a)'

When I run that, I get:

$VAR1 = {
          'one' => {
                     'a' => [
                              1,
                              2,
                              3
                            ],
                     'b' => [
                              4,
                              5,
                              6
                            ]
                   },
          'two' => {
                     'c' => [
                              7,
                              8,
                              9
                            ],
                     'b' => [
                              5,
                              6,
                              7
                            ]
                   }
        };
$VAR1 = [
          1,
          2,
          3
        ];
