form api radios?

  1.  $form['step1'] = array(
  2.     "#type" => "fieldset",
  3.     "#title" => t("What type of point would you like to add"),
  4.   );
  5.  
  6.   foreach ( $validtypes as $type => $info ) {
  7.     $form['step1']['type'][$type] = array(
  8.       '#type' => 'radio',
  9.       '#name' => 'type',
  10.       '#title' => $info['name'],
  11.       '#description' => $info['description'],
  12.       '#return_value' => $type,
  13.     );
  14.   }
  15.  
  16.   $form['step1']['default'] = array(
  17.     '#type' => 'checkbox',
  18.     '#title' => t('Please use this selection as my default'),
  19.     '#default_value' => 0,
  20.   );
  21.  
  22.   $form["submitbtn"] = array(
  23.     "#type" => "submit",
  24.     "#value" => t("Next")
  25.   );
  26.  
  27.   return $form;
  28.  
  29. The $_POST is how it should be:
  30.  
  31. (
  32.     [type] => article
  33.     [op] => Next
  34.     [form_build_id] => 35032606e64f1978fc8f61c4847bbcd3
  35.     [form_token] => 1a47ceb7ca7e361d4be1d97533ead120
  36.     [form_id] => imsaddpoint_pointform
  37. )
  38.  
  39. The $form_values is not correct:
  40. (
  41.     [contact] =>
  42.     [hca] =>
  43.     [default] => 0
  44.     [op] => Next
  45.     [submitbtn] => Next
  46.     [form_build_id] => 35032606e64f1978fc8f61c4847bbcd3
  47.     [form_token] => 1a47ceb7ca7e361d4be1d97533ead120
  48.     [form_id] => imsaddpoint_pointform
  49. )
