ASP not working inside of Accordian.

I am having an issue I am using an accordian sort of like a popup more options menu. I added some drop down boxes inside an accordian and it displays fine and shows the values. But when I try to build a function to send the drpVariable.SelectedValue is set to null. It seems that the default.aspx.cs does not capture the selected value inside the accordian. Does anyone know a work around this? Below is an example of some of the code

<

cc1:AccordionID="Accordion1"runat="server"AutoSize="Limit"style="z-index: 101; left: 845px; position: relative; top: -349px"Height="370px"Width="134px"><Panes><cc1:AccordionPaneID="dummy"runat="server"></cc1:AccordionPane><cc1:AccordionPaneID="apMsgSearchOptions"runat="server"><Header><ahref=""onclick="return false;">Search Options</a></Header></cc1:AccordionPane><cc1:AccordionPaneID="apMsgAdvancedSearch"runat="server"><Header><ahref=""onclick="return false;">Advanced Search</a></Header><Content><asp:LabelID="lblMsgKeyClient"runat="server"Text="Client"/><br/><asp:TextBoxID="txtMsgKeyClient"Width=45pxEnabled="false"MaxLength="5"runat="server"/><br/><asp:LabelID="lblMsgKeyStartDate"runat="server"Text="Start Date"/><br/><asp:TextBoxID="txtMsgKeyStartDate"Width=45pxEnabled="false"runat="server"/><br/><asp:LabelID="lblMsgKeyEndDate"runat="server"Text="End Date"/><br/><asp:TextBoxID="txtMsgKeyEndDate"Width=45pxEnabled="false"runat="server"/><br/><asp:LabelID="lblMsgKeyMsgCategory"runat="server"Text="Msg Category"/><br/><asp:DropDownListID="drpMsgKeyMsgCategory"runat="server"Width="50px"><asp:ListItemSelected="True"></asp:ListItem><asp:ListItem>A</asp:ListItem><asp:ListItem>B</asp:ListItem><asp:ListItem>C</asp:ListItem><asp:ListItem>D</asp:ListItem><asp:ListItem>E</asp:ListItem><asp:ListItem>F</asp:ListItem><asp:ListItem>Z</asp:ListItem><asp:ListItem>1</asp:ListItem><asp:ListItem>2</asp:ListItem><asp:ListItem>3</asp:ListItem><asp:ListItem>4</asp:ListItem></asp:DropDownList><br/><asp:LabelID="lblMsgKeyMsgType"runat="server"Text="Message Type"/><br/><asp:DropDownListID="drpMsgKeyMsgType"runat="server"Width="75px"><asp:ListItemSelected="True"Value="H">Hour</asp:ListItem><asp:ListItemValue="5">5 Min</asp:ListItem><asp:ListItemValue="1">1 Min</asp:ListItem></asp:DropDownList><br/><asp:LabelID="lblMsgKeyProductCode"runat="server"Text="Product Code"/><br/><asp:DropDownListID="drpMsgKeyProductCode"runat="server"Width="75px"><asp:ListItemSelected="True"></asp:ListItem><asp:ListItem>DMS</asp:ListItem><asp:ListItem>RTDS</asp:ListItem><asp:ListItem>XMLM</asp:ListItem></asp:DropDownList><br/><asp:LabelID="lblMsgKeyRequestType"runat="server"Text="Request Type"/><br/><asp:DropDownListID="drpMsgKeyReqType"runat="server"Width="75px"><asp:ListItemSelected="True"></asp:ListItem><asp:ListItemValue="A">Alpha</asp:ListItem><asp:ListItemValue="E">Event</asp:ListItem><asp:ListItemValue="I">Inquire</asp:ListItem><asp:ListItemValue="M">Maint</asp:ListItem><asp:ListItemValue="P">Publish</asp:ListItem><asp:ListItemValue="-">Error</asp:ListItem></asp:DropDownList><br/></Content></cc1:AccordionPane>

Just an update I added a dropdown reading an XML file... and all the drop down boxes worked then. Can anyone explain why it now works and didnt without when all the dropdown had list items.
