Form results not displaying - D7
Added type markup below the submit code in $form_state['storage']['results'] and that does the trick...

  $form['submit'] = array(
    '#value' =&gt; 'Search',
    '#type' =&gt; 'submit',
  );

if(isset($form_state['storage']['results'])) {
        $form['result'] = array
        (
          '#type' =&gt; 'markup',
          '#markup' =&gt; t('The results of the form are: !results', array('results' =&gt; $form_state['storage']['results'])),
        );
      }
