Select ddl item based on the url

Hello all, On my contact page (contact.aspx)I have a booking form that contains a drop down list control which is dynamically populated with the names of the available drivers. What I would like to do is on each drivers individual page e.g driver1.aspx provide a book this driver link which when the user selects it they are taken to the contact page and the drop down list pre populated with the drivers name of the page they have just come from. Can this be achieved? If so has and one got any links or advice on how to do it? Thanks Paul
