Hi
In the code that you suggested, I HAVE to include the : for keys %{$mappings{$key}}; at the end of print statement.
I did this: 
for my $key (keys %mappings) {
            print "$key - $mappings{$key}{$_} -> $_\n"  for keys %{$ma
+ppings{$key}} if ($mappings{$key}{$_} > 1);
    }

But the code still doesn't work.
The error message is: 
syntax error at test.pl line 33, near "} if"

Thanks
