Hello Monks, I have following code in script.pl(this is only part): 
my $i = 'Insert';
$i->dodaj_narzut($products_price, \%zakresy)

[download]
There is following code in package "Insert.pm": 
sub dodaj_narzut {
  my ($class,$cena,$zakresy) = @_;
  my $narzut = $class->ret_narzut($cena,$zakresy);
  my $new = sprintf('%.2f', $cena+($cena*($narzut/100)));
  return $class->zaokraglenie($new);
}
sub ret_narzut {
  my ($class,$cena,$zakresy) = @_;
#   use Data::Dumper;
#   print Dumper($zakresy);
  while (($zakres,$wartosc) = each %$zakresy) {
    my @zak = split '-', $zakres;
    if ($cena > $zak[0] and $cena <= $zak[1]) {
      return $wartosc;
    }
  }
  print "55\n";
  return 55;
}

The problem is that in subroutine "dodaj_narzut" half of the time it's like hash reference doesn't exist. It skips while loop. Next time when subroutine is executed it works perfectly - it goes through while loop and returns proper "$wartosc". But if I uncomment "Use Data::Dumper" and "print Dumper($zakresy)" while loop is executed every time. When I resign on using references it also works OK every time. It must be something with the references.

Thank you for any help.
Best regards,
Jerzy
