Try this

    $('#txtSelect').val($('#multiSelect').val());
   });

Based off a hint from jMar's blog:

$("#multipleSelect").change(function() {
  $("#textBox").val("");
  $("#multipleSelect option:selected").each(function(i) {
    if (i > 0)
      $("#textBox").val($("#textBox").val() + ", " + $(this).text());
    else
      $("#textBox").val($(this).text());
  });
});

If you don't need the commas/separators, it's actually just:

$("#multipleSelect").change(function() {
  $("#textBox").val($("#multipleSelect option:selected").text());
});

Fiddle with it over at jsfiddle.
