Witam.

Mam formularz w którym pole select z miastami, gdzie po wybraniu regionu ładuje się dynamicznie za pomocą Ajax.
Nie wiem dlaczego formularz nie przesyła wybranej opcji z pola select (miasta), w ogóle nic nie przesyła tak jakby tego pola nie było.

Dodam, że przed wybraniem regionu, pole select (miasta) jest ładowane przez php z domyślnymi opcjami i w momencie wysłania dane z niego są przesyłane.

Kod formularza:
<form action="?" method="get" id="CountryForm" name="CountryForm" style="border:none" onSubmit="nieaktywne();">
