Hi Himaja,

Could you show us your hash with Data::Dumper? E.g. use Data::Dumper; print Dumper(\%hash);

You check for definedness with defined, e.g. if (!defined $hash{key}). One way to check for an empty string is with length, e.g. if (!length $hash{key}), but make sure to check defined first, because length(undef) will also be false (and before Perl v5.12, will throw a warning).

Hope this helps,
