Error: "Map container is already initialized."

Perhaps pastebin the code (or if it's small, add it as a comment here - Richard's example here is only 15 lines long, after all)

Hi,

The code is as follows, it is the basic code example. it does sit within a page that also does a JSON call etc.

Much appreciated!

    <script src="leaflet/dist/leaflet.js"></script>

    <div id="map" style="height: 200px"> <a href="#" data-role="button" id="getLocation">Get my location</a> </div>

    <script>

            $('#getLocation').click(function(){

            map = new L.Map('map');

            var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/myapikey/997/256/{z}/{x}/{y}.png',
            cloudmadeAttribution = 'Map data &copy; 2011 OpenStreetMap contributors, Imagery &copy; 2011 CloudMade',
            cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18, attribution: cloudmadeAttribution});
            map.setView(new L.LatLng(51.505, -0.09), 13).addLayer(cloudmade);

            var markerLocation = new L.LatLng(51.5, -0.09),
            marker = new L.Marker(markerLocation);
            map.addLayer(marker);
            marker.bindPopup("<b>Hello world!</b><br />I am a popup.").openPopup();

            });
