I am having trouble passing custom data through theme() to a custom callback and passing the data through to a tpl file. Here is my code:

hook_theme:

function satb_schedule_theme() {
  return array(
    'satb_schedule_brackets' => array(
      'render element' => 'bracket',
      'variables' => array('bracket' => array()),
      'template' => 'satb_schedule_brackets',
      'path' => drupal_get_path('module', 'satb_schedule') . '/templates',
    )
  );
}

hook_menu item:

$items['tournaments/%/%/schedule/winner-bracket'] = array(
    'title' => 'Winner Bracket',
    'description' => 'View the winner brackets for this tournament.',
    'page callback' => 'satb_schedule_generate_bracket',
    'page arguments' => array(1, 2, '0'),
    'weight' => -16,
    'type' => MENU_LOCAL_TASK,
    'access arguments' => array('view tournament brackets'),
  );

hook_menu item callback (satb_schedule_generate_bracket):

function satb_schedule_generate_bracket($nid, $product_id, $bracket_type) {
  $schedule = new SATBScheduleDisplay(array('nid' => $nid, 'product_id' => $product_id));
  return $schedule->getTournamentBracket($bracket_type);
}

This function generates an array of data. Inside of the method, data is gathered and returned through theme(), like so:

$output = theme('satb_schedule_brackets', array('bracket' => $brackets));
return $output;

In the template.php, I have this to modify and add variables for the template:

function satb_preprocess_satb_schedule_brackets($variables) {
  $brackets = $variables['bracket'];

  foreach($brackets as $key => $round) {
    switch ($key) {
      case 3:
        $classes = array('round', 'quarterfinal');
        $round_title = t('Quarter Finals');
        break;
      case 2:
        $classes = array('round', 'semifinal');
        $round_title = t('Semi-Finals');
        break;
      case 1:
        $classes = array('round', 'final');
        $round_title = t('Final');
        break;
      default:
        $classes = array('round');
        $round_title = t('Round @round_number', array('@round_number' => $key));
        break;
    }

    $variables['bracket'][$key]['data'] = array('classes' => implode(' ', $classes), 'round-title' => $round_title);
  }

  $vars['bracket'] = $variables['bracket'];
  $vars['tournament_title'] = 'Just a test';
  return $vars;
}

My custom tpl is loaded (I can see the static HTML in there as a test and print static vars) however, my modifications don't seem to get passed to the template.

For example, if I do print $tournament_name;, its null. If I do print $bracket['tournament_title']- it appears, but I don't want to access variables like that because that's messy, and, it should respect the vars I am adding to the vars array.

What am I missing here? The classes and titles I am adding in the preprocess are also missing in the $bracket element in the TPL. The $vars has them, but the TPL does not.

Doh. $variables is passed by reference. I always forget this in template.php:

function satb_preprocess_satb_schedule_brackets(&$variables) {
