Having trouble printing my theme from a custom module I created a custom tpl.php page with some basic HTML:

&lt;div id='test'&gt;TEST&lt;/div&gt;


And a module file that defines the theme:

function my_module_test_theme($existing, $type, $theme, $path) {
    $items = array();

    //Test
    $items['test_test'] = array(
        'template' =&gt; 'test-test',
        'path' =&gt; drupal_get_path('module', 'my_module') . '/templates',
    );

    return $items;
}


But when I try to print it out in my theme it doesn't work:

&lt;?php $output = theme('test_test'); ?&gt;


Am I printing out the theme in my site's theme's page.tpl.php incorrectly?
I forgot to echo $output.........
