This is probably something Drupal, but I can't seem to figure out what.  I have the following functions:  function farm_form_alter(&$form, &$form_state, $form_id) {


  $form['#validate'][] = 'testing_validation';
}

function testing_validation( $form, &$form_state) {
  echo '<pre>'; print_r($form_state["values"]); echo '</pre>'; 
}
I know they are both running, but the values array that gets printed out never has the form inputs.  What am I doing wrong?
