I'm getting this error that I'm not sure how to fix:
$> ./datalink.pl > out.txt
Can't use string ("389/1024") as a HASH ref while "strict refs" in use
at ./datalink.pl line 41, <$SUM> line 4060.
code snippet:
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($_), keys %$href; # <-- line 41
foreach ( @wanted ) {
print "$_:\n";
foreach (values %{ $href->{ $_ } } ){
print "\t$_\n";
}
}
