Hi,

I've successfully set up on my website the example geocoded googlemap with markers from here:

http://code.google.com/support/bin/answer.py?answer=65622

I now want to add a search box to geocode a typed in location, and re-center the map on that location. The following code works fine:

    <script type="text/javascript">

      var map = null;
      var geocoder = null;

      function load() 
      {
        if (GBrowserIsCompatible()) 
        {
          map = new GMap2(document.getElementById("map"));        
          map.setCenter(new GLatLng(53.799637, -1.54911), 6);
                
          geocoder = new GClientGeocoder();
        }
      }
    
      function findAddress(anAddress)
      {
        if (geocoder) 
        {
          geocoder.getLatLng(anAddress, function(aPoint) 
          {
            if (!aPoint) 
            {
              alert("Sorry, can't locate [" + anAddress + "]");
            } 
            else 
            {
              map.setCenter(aPoint, 13);
              var elem = document.getElementById("latLng");
              elem.innerHTML = aPoint.lat() + ", " + aPoint.lng();
            }
          });
        }
      }

    </script>
  </head>

  <body onload="load()" onunload="GUnload()">
    <form action="#" onsubmit="findAddress(this.address1.value); return false">
      <p>
        <input type="text" size="60" name="address1" value="Type in city/town/village or postcode" />
        <input type="submit" value="Go!" />
      </p>
      <div id="map" style="width: 500px; height: 500px"></div>
      <p>Latitude/Logitude: <span id="latLng">51.500789, -0.142264</span></p>

    </form>
  </body>
</html>

However, when I try to insert this code into the map with markers, it doesn't work. When the location is typed into the search box, the map does not re-center. I've looked at the code until I've gone cross-eyed, and I just cannot figure out why it doesn't work. If anyone can help, I'd be really grateful.

Thanks

Here's the non-working code:
