I have my hash with the following structure - not sure it is the good one, considering I want $topic, and $index be also keys -
$bighash{$key1}{$key2}{$key3}{$key4}[$topic-1][$index-1] = $total;

[download]
The hash: keys 50:20:6:4, topic 1, and 5 index with its totals and so on 
$VAR1 = {'50' -> {
..........'20' -> {
.............'6' -> {
...............'4' -> |
...................|
....................'30',
....................'40',
....................'20',
....................'20',
....................'10'
....................|,

....................|

....................'28',
....................'10',
....................'76',
....................'20',
....................'10'
....................|,

........{'60' => {
..........'30' => {
............'6' => {
...............'4' => |

                       |

....................'30',

For each set of keys in specific $topic I have a set of index: index1, index2, index3...indexN and its total I want to sort the $index by the value of its $total, without affecting the order of the $keys and $topic and return... 
$VAR1 = {'50' => {
...........'20' => {
............'6' => {
.............'4' => |

.....................|

....................'40',=>index2
....................'30',=>index1
....................'20',=>index3
....................'20',=>index4
....................'10'=>index5
.....................|,

I wrote the word "index.." besides each total as an example, because I need to keep track of which index was, as another key. So maybe my initial hash structure was not ok.

How do I sort those values without affecting the whole hash structure?, and is it my hash structure? OK?

Thanks
