<script language="javascript" type="text/javascript">
// <=!=[=C=D=A=T=A=[
var SelectedState;
function state_onchange() {
var index = state.selectedIndex;
if (SelectedState != null) {
SelectedState.setAttribute("hidden", "hidden");
}
switch (index) {
case 0: SelectedState = Select1;
break;
case 1: SelectedState = Select2;
break;
case 2: SelectedState = Select3;
break;
case 3: SelectedState = Select4;
break;
case 4: SelectedState = Select5;
break;
case 5: SelectedState = Select6;
break;
case 6: SelectedState = Select7;
break;
case 7: SelectedState = Select8;

case 8: SelectedState = Select9;
