Problem with Uploading two images, re-sizing them, and saving them to the database

[eluser]RMinor[/eluser]
Hi, I have an issue with uploading two images, re-sizing them, and saving them to the database. When I submit the form I get an error stating that 'photo_one, 'thumb_one', 'photo_two', and 'thumb_two' are undefined indexes. It's like they aren't even being passed. Can anybody see what's going on with my code below?

Controller:

Code:

public function index()
{
  $this->load->model('Model_model');
  $data['page'] = $this->Global_model->pageInformation($this->_page);
  $data['testimonials'] = $this->Model_model->getTestimonials();
  $data['success'] = FALSE;
  $this->load->helper('form');
  $this->load->library('form_validation');
  $this->form_validation->set_error_delimiters('<div class="error">', '</div>');
  if ($this->input->post('submit')) {
   $this->form_validation->set_rules('name', 'Name', 'trim|required');
   $this->form_validation->set_rules('stage_name', 'Stage Name', 'trim');
   $this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email');
   $this->form_validation->set_rules('birth_month', 'Birth Month', 'trim|required|integer|exact_length[2]');
   $this->form_validation->set_rules('birth_day', 'Birth Day', 'trim|required|integer|exact_length[2]');
   $this->form_validation->set_rules('birth_year', 'Birth Year', 'trim|required|integer|exact_length[4]');
   $this->form_validation->set_rules('photo_one', 'Photo', 'trim');
   $this->form_validation->set_rules('photo_two', '', 'trim');
   $this->form_validation->set_rules('age_check', 'Age Check', 'trim|required');
   $this->form_validation->set_rules('ip', 'IP Adress', 'trim|required|valid_ip');
   if($this->form_validation->run() == FALSE) {} else {
    if ($this->upload()) {
     $email = $this->input->post('email');
     $body = "<p></p>"
     $this->load->library('email');
     $this->email->from('', '');
     $this->email->to($email);
     $this->email->cc('');
     $this->email->subject('');
     $this->email->message($body);
     if ($this->email->send()) {
      $data['success'] = TRUE;
     }
    }
   }
  }
  $this->load->view('model_view', $data);
}

Model:
