Incluyo dos capturas de pantalla, para explicarme mejor:
Esta es la imagen que se muestra:
http://dl.dropbox.com/u/4582191/Pantallazo1.png
Y esta es la banda 1 que se debiera mostrar:
http://dl.dropbox.com/u/4582191/Pantallazo2.png
Debo modificar algo de la cabecera para que se muestre correctamente?
Hay algún modo de modificar la importación?
Saludos.
