Iterate over the result:

   for my $cell ( sort keys %sum ) {
     for my $sect ( sort keys %{$sum{$cell}} ) {
       for my $chan ( sort keys %{$sum{$cell}{$sect}} ) {
           print "Value of sum($cell,$sect,$chan) is
$sum{$cell}{$sect}{$chan}\n";
       }
     }
   }

And Data::Dumper could help you find out the complicated data structure.
