Fellow monasterians,
I'm learning new DBI schemes and have been working with fetchall_arrayref. It works fine as shown, but would like to know how to access the data (see example A), intercepting it, as it were, to manipulate it before committing it to $template -> param(...). The methods are not working and get output like "HASH(0x8301bb8)" and "Not an ARRAY reference." I found thisand this, but not getting any results. Aren't I just deferencing the array? Or is this acting like a hash? Is it even possible? Thanks all!

This works fine (I get populated drop downs in my HTML form): 
my $stmt = "SELECT DISTINCT scene, title  FROM catalog";
my $sth = my $dbh->prepare($stmt) or die ...r";
$sth->execute() or die ...r"

my $data   = $sth->fetchall_arrayref({});
my $template -> param ( selscene => $data );

Example A: 
my $data   = $sth->fetchall_arrayref({});

if ( $data->[1] eq "large" ) {    #something like this or...
   ucase ( $data->[1] );
}

print $data->[1],"\n";    #can I even print it

$template->param(selscene => $data)

FYI, here's the HTML: 
<select name="scenes">
   <tmpl_loop name="selscene">
      <option value="<tmpl_var scene>"><tmpl_var title></option>
   </tmpl_loop>
</select>
