ASPX form doesn't send any dropdown or listbox data

[netspace]

I am new to .net and would appreciate some advice.
All of the form results are sent, except the DropDownList and ListBox.
code is;
<asp:DropDownLi st id="Hear_About_ Us" Tabindex="85" runat="server">
<asp:listitem Text="Select one" value="Select_o ne" />
<asp:listitem Text="Direct Mail" value="Direct Mail" />
<asp:listitem Text="Networkin g" value="Networki ng" />
<asp:listitem Text="Trade Show" value="Trade Show" />
<asp:listitem Text="Web Search" value="Web Search" />
<asp:listitem Text="Establish ed Client" value="Establis hed Client" />
<asp:listitem Text="Other" Value="Other" />
</asp:DropDownLis t>

<asp:DropDownLi st id="product_use _1" runat="server">
<asp:listitem Text="Select one" value="Select_o ne" />
<asp:ListItem Text="Trade Show" value="Trade_Sh ow" />
<asp:ListItem Text="Special Event" Value="Special_ Event" />
<asp:ListItem Text="College/School" Value="College/School" />
<asp:ListItem Text="General Use" Value="General_ Use" />
<asp:ListItem Text="Other" Value="Other" />
</asp:DropDownLis t>

I guess I am missing something but Expressions doesn't help much.

So, where's the part that sends the values? This doesn't tell us anything. Show us the part that handles the sending and we can give it a try.
