Linking to a url through a selection list

I have routes.rb set up so that when I go to it goes
directly to a person’s public page:

map.connect ‘:name’, :controller => ‘main’, :action => ‘page’

Now, I want a selection list, that when a name is selected and submitted
will go to that page. So if “Bob” is selected, it will go to

Let’s just say there is a Person object with a :name field.

Thank you for any help.
