Give this one a try: http://jsfiddle.net/ufomammut66/mw4dY/

Basically onload I'm just selecting an option by the value, setting it to selected and then calling the change event. Your change event takes care of the rest.

$(document).ready(function() {                                       
  $("#name").live("change", function() {
    $("#firstname").val($(this).find("option:selected").attr("value"));
  });
  $('#name option[value=Frank]').attr('selected','selected').change();
});
