references are still a bit foreighn to me. Below is the error I am
getting along with the snippit of code.
Can't use string ("ND") as a HASH ref while "strict refs" in use at
./datalink.pl line 48, <$SUM> line 4060.
my $href = \%data;
sub ND_or_multiple {
my %uniq;
for (values %{$href->{$_[0]}}) {
return 1 if $_ eq 'ND';
$uniq{$_}++;
return 1 if keys %uniq > 1;
}
return '';
}
my @wanted = grep ND_or_multiple($_), sort keys %$href;
foreach my $cell ( @wanted ) {
print "$cell:";
foreach my $hr ( sort keys %{ $href->{$cell}} ) {
# print "\t$hr";
foreach my $count ( sort keys %{ $href->{$cell}->{$hr}} ) { # <-- line 48
print "\t$count";
}
}
print "\n";
}
Thank you,
Chris
