in reply to Re^4: NOT seeing data in HoH
in thread add data to HoA

If you're going for a HoH, you'll need keys for each value in the inner hash (like you're using $date as a key in the outer hash). Instead of:
$GSPmsgHash{$date} = { $alertLv, $src, $srcD, $probD, $days_between, }
You probably want:
$GSPmsgHash{$date} = { alert_level => $alertLv, source => $src, source_detail => $srcD, problem_detail => $probD, days_between => $days_between, }
This way, to get the alert level for $date, you would do the following:
my $alert_level = $GSPmsgHash{$date}->{alert_level};

    OK I can make that work the way you showed, but I am still wondering why days_between only shows up when I use Data::Dumper. Nevermind I got it working: with: Thx agn!
    for my $k (keys %GSPmsgHash) { print "$k =>\n"; for my $v (values %{$GSPmsgHash{$k}} ) { print " $v\n"; } }
