    You can achieve this easily using jQuery. Since we don’t have much information about your HTML I present a more generalized solution.

    Add the following to your <head>:

    <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>

    (or download the .js file and point to it’s local path)

    Then add something along these lines also on the <head> of your document:

    $(document).ready(function()
{
    $("#selectID").change(function()
  {
      //Reset any select boxes
      $("#selectOther")[0].selectedIndex = 0;
  });
});

    You can see a working example at http://jsfiddle.net/zPhnN/1/

    This should be modified to suit your needs, but hopefully it’s something to get you started.
