Siblings, I've got a nasty feeling this is going to be one of those nodes that stands as a lasting monument to my inability to see what's in front of my nose. But. I've got a data structure that prints out like this from Data::Dumper (just to be sure it really is the structure I want): 
$VAR1 = {
          '1' => {
                   '1' => {
                            'EMail' => 'norbert@thnwb.com',
                            'Name' => 'Norbert Bodkin'
                          },
                   '5' => {
                            'EMail' => 'sue@thnwb.com',
                            'Name' => 'Sue Soup'
                          }
                 },
          '2' => {
                   '3' => {
                            'EMail' => 'max@thnwb.com',
                            'Name' => 'Max Grappler'
                          }
                 }
        };

Now, say I want to print out everyone's name, ordered first by the key of the "outer" hash and then by the next hash in (i.e. in this case exactly the order you see them above) I tried to do: 
106    my $status;
107    for $status (keys %Status) {
108        for (keys %{ $Status{$status} }) {
109            print $Status{$status}{$_}{'Name'}, br;
110        }
111    }

(line numbers added for clarity) BUT... I get Can't use string ("1") as a HASH ref while "strict refs" in use at /home/htdocs/hosted/thinweb/lib/devbox.pm line 108. I tried a few other lame ways to do it which I won't go into her, but when I RTFMed, I found that my first cut was pretty much the staff solution... as far as I could tell. I even got superstitious and tried 
105    my $status;
106    my $id;
107    for $status (keys %Status) {
108        for $id (keys %{ $Status{$status} }) {
109            print $Status{$status}{$id}{'Name'}, br;
110        }
111    }

... nada.

I'm stumped... I crave enlightenment... no matter how humiliating.
