Need syntax to submit a new form entry

Tony,
Try letting Rails generate the route. I'm not sure exactly what
you're doing, but the view should probably look a little more like
this:

<% form_tag :action => 'create' do %>
  <%= hidden_field_tag "roster[id]", @roster.id %>
  <%= submit_tag 'Create' %>
<% end %>

Make sure your controller has a corresponding 'create' action.
