I have 3 dropdowns , one for each Year, Month, Day.When user selects Year and month , day should fill according to Year and month calculation.
I am using following script for doing same.But "Object not found" error coming.
Please help me in solving problem.

function AddItem()
{
var opt = document.createElement("option");
document.getElementById("ddDay").options.add(opt);
opt.value = validateDays();
}
function validateDays() {
var y = document.getElementById('<%= ddYear.ClientID %>').selectedIndex;
var m = document.getElementById('<%= ddMonth.ClientID %>').selectedIndex;
if (m == 01 || m == 03 || m == 05 || m == 07 || m == 08 || m == 10 || m == 12) {
var dmax = 31;
return dmax;
}
else if (m == 04 || m == 06 || m == 09 || m == 11) {
var dmax = 30;
return dmax;
}
else {
if ((y % 400 == 0) || (y % 400 == 0 && y % 100 != 0)) {
dmax = 29;
return dmax;
}
