How do I get selectevalue from DDL into ODS insert?

I have a form with an objectdatasource in it and three simple controls. I want to insert the selectedvalue from a databound dropdownlist into the objectdatasouce insert parameter "CommitteeID". I've tried several different ways and it's just not working. This is the latest iteration:

EVerything else works, but the selected value of the dropdownlist. It's almost like the insert happens in the page cycle prior to the dropdownlist selectedvalue coming back from viewstate. Please help. This is driving me crazy. This should be VERY simple.

<table style="width: 100%">
        <tr>
            <th>
                Committee:
            </th>
            <td>
                <asp:DropDownList ID="ddlCommittee" runat="server" DataSourceID="odsCommittees" DataTextField="CommitteeName"
                    DataValueField="CommitteeID" EnableViewState="true">
                </asp:DropDownList>
            </td>
        </tr>
        <tr>
            <th>
                Question:
            </th>
