in reply to getting values from a hash element???

Without seeing the rest of your code, I'll venture this response.

In the code you displayed here, $self->{TABLE} is a reference to a hash element, and if it's the hash being referenced by "$self" that you wish to retrieve the values from, then you merely need to dereference the hash like this:

my @TABLE_ARRAY = values ( %{$self} );

Which will get you back the values ("val1", "val2", "val3") from a structure that looks like this:

$self = { "key1" => "val1", "key2" => "val2", "key3" => "val3", };

If, on the other hand, $self->{TABLE} contains a reference to another hash as it's value, and that is what you're after, then you'll need to dereference it like this:

my @TABLE_ARRAY = values ( %{$self->{TABLE}} );

which will get you back the values ("val1", "val2", "val3") from a structure that looks like this:

$self = { "TABLE" => { "key1" => "val1", "key2" => "val2", "key3" => "val3", } };

Study up on perlref, and I would also highly recommend you take a look at Data::Dumper which lets you print them out and have a peek.
