I have a problem with accessing data from a 3D hash. I've tried scaling the hash structure from a 2D hash, whcuh I can access fine via nested for loops. However, I can't get access a 3D hash. I'd like some help, please. Here's my code, (also posted on my scratchpad): 
%ThreeD = (
        TV => {
       version3 => {
                lead      => "fred",
                pal       => "barney",
       },
        },
 );

# print the whole thing
foreach $media ( keys %ThreeD) {
     print "$media @ {";
     for $media_ver ( keys %{ $ThreeD{$media_ver} } ) {
    print "$media_ver { ";
    for $leaf_obj ( keys %{ $ThreeD{$media{$media_ver}} } ) {    
           print "$leaf_obj=$ThreeD{$media}{$media_ver}{$leaf_obj} ";
    }
     }
     print "}\n";
}

Perhaps I have constructed the hash incorrectly? I feel the answer is more likely that my inner loop 'for' is set up incorrectly or that its inner-most print statement is incorrect. I searched all over for an example of a 3D hash, but have found nothing. Is this possible in Perl!!?!?
