fellow monks: a little background before the question:

1) say i have a hash like this:
%goodhash = (
         red   => '1',
         blue  => '2',
         green => '3',
);

@colors = qw(red blue green);

print $fh join("|", @hash{@colors}), "\n"

--->writes a line "1|2|3\n" no problem

2) now the question, what if i have a hash of hashes
say something like
$evilhash{$id} = {
                 red   => '1',
                 blue  => '2',
                 green => '3',
};

@colors = qw(red blue green);

[download]

but it complains about undef ARRAY ref when i do
print $fh join("|", @evilhash{$id}{@colors}), "\n"

or this @{$evilhash{$id}}{@colors}

[download]


read thru the perldsc,etc but no success

any advice please?
