if (form_name.pay_method.value=="eCash") {
document.getElementById("paybycash").style.display = "block";
document.getElementById("paybycard").style.display = "none";
} else {
document.getElementById("paybycash").style.display = "none";
document.getElementById("paybycard").style.display = "block";
}
