Getting data from submitted form
Check your variables by printing them with drupal_set_message().

function multi_reg_pagecreate_submit($form, &amp;$form_state) {
  drupal_set_message('&lt;pre&gt;' . print_r($form_state['values'], true) . '&lt;/pre&gt;');
}


Alternatively, you can use debug()

debug($form_state['values'], 'Debugging the form', TRUE);
