Set Radiobuttonlist Value via Javascript

Hi all,

I have two radiobuttonlist controls on a page. When a user checks 'No' for
rblDeleted, I want to automatically set rblSendCard to 'No' and disable it.
The javascript function I wrote to do this 'appears' to work on the screen,
however, when the page is posted back and I check the value of rblSendCard,
it is an empty string when I expect it to be 'N'.
Of, course I can work around the problem by assuming 'N' when it is an empty
string, but would prefer to have the correct value posted back.

Can anyone tell me how to get it to work the way I expect or explain why it
can't.
Code is below.
TIA

<asp:radiobuttonlist id="rblSendCard" tabIndex="13" runat="server"
RepeatDirection="Horizontal" CellPadding="0"
CellSpacing="0" EnableViewState="False">
<asp:ListItem Value="Y">Yes</asp:ListItem>
<asp:ListItem Value="N">No</asp:ListItem>
</asp:radiobuttonlist>
<asp:radiobuttonlist id="rblDeleted" tabIndex="14" runat="server"
RepeatDirection="Horizontal" EnableViewState="False"
CellPadding="0" CellSpacing="0">
<asp:ListItem Value="Y">Yes</asp:ListItem>
<asp:ListItem Value="N" Selected="True">No</asp:ListItem>
</asp:radiobuttonlist
<script language="JavaScript"> function SetDeleted() {
if(document.getElementById('U_Members1_rblDeleted_ 0').checked){
document.getElementById('U_Members1_rblSendCard_1' ).checked=true;
document.getElementById('U_Members1_rblSendCard'). disabled='disabled';}
else{
document.getElementById('U_Members1_rblSendCard'). disabled='';}}</script

Thanks for the quick reply, Bill.

That certainly explains it.
