Custom Fields In Checkout Preview not showing up

I followed all of the directions here:  
www.sitefinity.com/.../adding-custom-fields-to-the-checkout-widget

and I can't seem to get my custom fields to show up on the  summary widget.

Setting breakpoints in Global.asax is see that the fields are set  (they happen to be on the Shipping Options page) and in the code it looks like the  save  goes ok.

Over on the Order Preview I try to display my custom fields and see nothing.
Other than modifying the template to display them, do i need any other code behind ?

In the Preview Template I have tried both:
Look:<%# Eval("Notes") %>
and
 <asp:Literal ID="MyNotes" runat="server" Text='<%# Eval("Notes") %>' />

What am I missing or doing wrong ?

Thanks,
Tim

Did you get a response? I'm trying to do the same thing on preview (cartorder custom field), also on shoppingcart template (cartitem custom fields). Got email figured out I think.

I ended up doing it on the code behind for that widget.
