FindControl Issue

I think the issue I am having is as a result of how deep the "findcontrol" needs to go, I cant figure it out.
The page code is:
<asp:LoginView ID="LoginView1" runat="server">
            <RoleGroups>
            <asp:RoleGroup Roles="Admin">
            <ContentTemplate>
            <h3 style="font-style:oblique;font-weight:bold;">This is the Admin section</h3>
            <br /><br />
                <asp:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0" >
          &nbs ...
