document.getElementsByName("SELECT") dotyczy nazw "SELECT", "OPTION", "INPUT" itp.


Radziłbym posłużyć się:

<select id="property_estate_type_id">
i
document.getElementByID("property_estate_type_id")


// odczytanie numeru wybranej opcji
property_estate_type_id.selectedIndex

// odczytanie tresci z value wybranego selecta
mem=property_estate_type_id.value;

alert(mem)

Andrzej.
