Adding a user to a role using CreateUserWizard

 Hello,
I am trying to add a user to a role using the asp.net CreateUserWizard control.  The roles are programmatically databound to a CheckBoxList in the PageLoad event.
I have something like this.... 
               <asp:CreateUserWizardStep ID="CreateUserWizardStep1" runat="server" Title="Step 1: Basic User Information">
                    <ContentTemplate>
                                ......
                        <table >
      &nbs ...
