All help apprecaited!

You may want to check out the following example. I believe it should be self explanatory for you to follow:

<!DOCTYPE html>
<html> 
<head> 
    <meta http-equiv="content-type" content="text/html; charset=UTF-8"/> 
    <title>Google Maps API Geocoding Demo</title> 
    <script src="http://maps.google.com/maps?file=api&amp;v=2&amp;sensor=false"
            type="text/javascript"></script> 
  </head> 
  <body onunload="GUnload()"> 
    <div id="map_canvas" style="width: 400px; height: 300px"></div> 

    <script type="text/javascript"> 
       var geocoder = new GClientGeocoder();
       var map = new GMap2(document.getElementById("map_canvas"));
       var i;

       var postcodes = [
          'SL59JH',
          'LU13TQ',
          'SR29TD',
          'DA75BQ',
          'EC1V9B'
        ];

       map.setCenter(new GLatLng(54.00, -3.00), 5);

       for (i = 0; i < postcodes.length; i++) {
          geocoder.getLatLng(postcodes[i] + ', UK', function (point) {         
             if (point) {
                map.addOverlay(new GMarker(point));
             }
          });
       }
    </script> 
  </body> 
</html>
