Hi mhearse,

In your script you have table_data_begin_row and in your template you have table_data_begin_loop which may be part of the problem.

That particular var is hard coded into your script so you could put it in the template (also table_data_close_row).

I can't run your script to know if that is only snag but here's a snippet showing how I might do it. Notice the use of Data::Dumper which is excellent for these type of problems.

#!/bin/perl5

use strict;
use warnings;
use Data::Dumper;
use HTML::Template;
$Data::Dumper::Indent = 1;
$Data::Dumper::Sortkeys = 1;

my $data = [
  [qw{one two three}],
  [qw{four five six}],
  [qw{seven eight nine}],
];

my @outer_loop;
for my $outer (@{$data}){
  my @inner_loop;
  for my $inner (@{$outer}){
    push @inner_loop, {data => $inner};
  }
  push @outer_loop, {inner_loop => \@inner_loop};
}

print Dumper \@outer_loop;

my $param = {outer_loop => \@outer_loop};

my $tmpl = do{local $/;<DATA>};
my $t = HTML::Template->new(scalarref => \$tmpl) or die qq{tmpl obj fa
+iled\n};
$t->param($param);
print $t->output;

__DATA__
  <TMPL_LOOP NAME=outer_loop>
  ---------------------------
  <TMPL_LOOP NAME=inner_loop>
  <TMPL_VAR NAME=data>
  </TMPL_LOOP>
  </TMPL_LOOP>

output (Dumper output followed by H::T output):

$VAR1 = [
  {
    'inner_loop' => [
      {
        'data' => 'one'
      },
      {
        'data' => 'two'
      },
      {
        'data' => 'three'
      }
    ]
  },
  {
    'inner_loop' => [
      {
        'data' => 'four'
      },
      {
        'data' => 'five'
      },
      {
        'data' => 'six'
      }
    ]
  },
  {
    'inner_loop' => [
      {
        'data' => 'seven'
      },
      {
        'data' => 'eight'
      },
      {
        'data' => 'nine'
      }
    ]
  }
];
