Hi

You're almost there; HTML::Template expects always to get arrays of hashes to drive a TMPL_LOOP. Take another look at the section on TMPL_LOOP in the HTML::Template documentation, it should make it clearer. It'd be nice to be able to use something like Perl's $_ in a TMPL_LOOP, but this isn't possible in HTML::Template AFAIK - the value you want to print has to be value in a hash. As an example:

use strict;
use HTML::Template;
my $template_text;
{
    local $/;
    $template_text = <DATA>;
}

my $template = HTML::Template->new('scalarref' => \$template_text);
my $sections = [
    { 'section_name' => 'Foo',
      'sub_sections' => [
          { 'sub_section_name' => 'Foo part 1' },
          { 'sub_section_name' => 'Foo part 2' },
          { 'sub_section_name' => 'Foo part 3' }
      ]
    },
    { 'section_name' => 'Bar',
      'sub_sections' => [
          { 'sub_section_name' => 'Bar part 1' },
          { 'sub_section_name' => 'Bar part 2' },
          { 'sub_section_name' => 'Bar part 3' }
      ]
    }
];


$template->param('section_names' => $sections);
print $template->output;
