All good, it's working now after I've initialized the values :) the output is all the phone models in Uganda with the number of users having these phones. However, there are duplicates of models, with different values. Can you think of a way to add those values and have a unique model with all the values added up?

#!/usr/bin/perl use strict; use warnings; use diagnostics; open (IMEI, 'IMEI.txt'); open (TAC, 'tac.txt'); my %mapToModel; my %keyCount; my $key; my $model; my $subs; my $keyCount; my $mapToModel; my $count; my %dictionary; while (<TAC>){ $key = substr $_,0,8; $model = substr $_,9; $keyCount{$key} = 0; $mapToModel{$key} = $model; } close (TAC); while (<IMEI>){ $subs = substr $_, 0, 8; if(exists $keyCount{$subs}){ $keyCount{$subs} = $keyCount{$subs} +1; } } close (IMEI); foreach my $key (keys %keyCount){ if (exists $mapToModel{$key}){ $model = $mapToModel{$key}; $count = $keyCount{$key}; foreach my$model (keys ) if( $count !=0){ print "$count\t$model"; } } }
