Thanks! You are exactly right about why my scalar wasn't working; I was calling it as 'my ($var).' Can you give me a quick line on why I should/shouldn't have the parenthesis on that?

I seem to have the multi-data working now, and I'll show you what I did. I suspect it is pretty sloppy, un-idiomatic code, so any suggestions for a cleaner implementation are welcome. Here we are. First, my CSV format (for reference):

"PrimaryTest","normalSentiment","negSentiment","topics"
"a waste",-1,0,""

Now my code:

while (my $fields = $csv->getline( $data )) {
    my $word = $fields -> [0];
    my $pos_sent = $fields->[1];
    my $neg_sent = $fields->[2];
    my $topics = $fields->[3];
    my @word_info = ($pos_sent, $neg_sent, $topics);

    # Trying with a reference
    my $pnt_word_info = \@word_info;
    $trie->add_data($word => $pnt_word_info);

    my $info = $trie->lookup_data($word);
    printf "Just added %s\n Sentiment: %s \t Neg Sentiment: %s \t Topi
+c: %s\n", $word, $info->[0], $info->[1], $info->[2];
}
