How to pass data from a one form to another

[eluser]Linkark07[/eluser]
Found the last part of the issue: the function on controller for load the second form. Here is how I have it:

Code:

public function confirma_inscr(){
$data['titulo'] = 'Confirmar Inscripción';
$data['query'] = $this->participante_model->obtenerdatosgrupo($nombre);
  $this->load->view('confirmarcurso_view', $data);  
}

The message that appears when I try to load that page is: Message: Undefined variable: nombre
