... which is what I get when I try it on my system, with this code:

[%

cgihash = {
           'a' => 'newentry',
           'newbooking' => '1',
           'day' => '06',
           'monthdigit' => '02',
           'year' => '2008',
           'room' => '9',
           'gender' => 'male',
           'beds' => '3',
           'nights' => '2',
           'submit' => 'Book'
         };

%]

should tell me this is a hash:
[% cgihash %]

dump out the contents of the hash:
[% USE Dumper %]
[% Dumper.dump(cgihash) %]

Now give me the keys:
[% cgihash.keys %]

OUTPUT:

should tell me this is a hash:
HASH(0x287c4a0)

dump out the contents of the hash:

$VAR1 = {
          'monthdigit' => '02',
          'a' => 'newentry',
          'nights' => '2',
          'submit' => 'Book',
          'room' => '9',
          'newbooking' => '1',
          'beds' => '3',
          'day' => '06',
          'year' => '2008',
          'gender' => 'male'
        };


Now give me the keys:
ARRAY(0x28c7170)
