I've been trying to modify the code from the HTML::Template tutorial Specfically, I'm focusing on the below piece of code: 
my $rows = [
   map {
      my $row = $_;
      (++$i % 2)
         ? { ODD  => [ map { {VALUE => $_} } @{$row} ] }
         : { EVEN => [ map { {VALUE => $_} } @{$row} ] }
   } @{$data}
];

I would like to modify the (++$i % 2) line. I have a $results variable and would like to map to the ODD output when the $results var is greater than zero and to the EVEN when the $results var is less than zero. I tried just replacing (++$i % 2) with $results>0) but that didn't work. Any suggestions? Thanks.
