My code:

while (chomp(@field = split (/\t/, <RPTFILE>)))
    {

    
    
    my $fulllookupKey = $field[1]."\t".  $field[2]."\t". $field[3]."\t

    my $RescatKey = $field[0];
    my $RessubcatKey = $field[1];
    my $MasterSrkey = $field[2];


if (exists($output{$RescatKey}{$RessubcatKey}{$fulllookupKey}))       
+ 
    {
       $output{$RescatKey}{$RessubcatKey}{$fulllookupKey}->[0] += $fie
+ld[6];
       $output{$RescatKey}{$RessubcatKey}{$fulllookupKey}->[1] += $fie
+ld[7];
     }
     else
     {
       $output{$RescatKey}{$RessubcatKey}{$fulllookupKey}->[0] = $fiel
+d[6];
       $output{$RescatKey}{$RessubcatKey}{$fulllookupKey}->[1] = $fiel

       }     

    }   
   

    for my $k1 (sort keys %output){

    print "$k1\n";

    for my $k2 ( sort keys %{ $output{$k1} }  ) {

    print "\t$k2\n";

     for my $k3 ( sort keys %{ $output{$k1}{$k2} }  ) {
