validar lista de formulario al enviarlo

[MBT]

Ahí va el código del formulario. Ahora (para variar) el botón "enviar" no me chequea nada, manda todo en blanco y chau, pero eso lo tengo que reveer, de todas maneras, validar la lista JAMÁS LO LOGRÉ!
Gracias David!
PD. saqué algunos paises pues no podía mandar un mensaje con tantos caracteres en el foro, no es nada personal.
