Google Maps JS

[ziycon]

I'm not sure if anyone here would know anything about the google map js, i've tried the google maps api community with no luck.

I have the below code, it loads ok, but when i click on the map it
doesn't place a marker.
What should happen is that when you click on the map it should place a
marker and when clicked on the map a second time that it should place
a marker at the new location and remove the previous one so that there
is only ever one marker on the map??

<script type="text/javascript"> 
 
    //<![CDATA[ 
         function createMarker(point,name) { 
         var marker = new GMarker(point,{title:name}); 
         return marker; 
     } 
     function mapclick(ov,pt) { 
         if (marker) map.removeOverlay(marker); 
         if (pt) { 
                         marker = createMarker(pt,pt.toUrlValue()); 
             map.addOverlay(marker); 
         } 
         var match11 = /\(([-.\d]*), ([-.\d]*)/.exec(pt); 
         if (match11) { 
                         var lat = parseFloat( match11[1] ); 
                         var lon = parseFloat( match11[2] ); 
                         lat = lat.toFixed(6); 
                         lon = lon.toFixed(6); 
         } 
         document.getElementById("lat").value = lat; 
         if(document.getElementById("lat").value == "undefined") { 
                         document.getElementById("lat").value = ""; 
         } 
         document.getElementById("lon").value = lon; 
         if(document.getElementById("lon").value == "undefined") { 
                         document.getElementById("lon").value = ""; 
         } 
     } 
     function load() { 
                 if (GBrowserIsCompatible()) { 
                         var map = new GMap2(document.getElementById("map")); 
                         map.setCenter(new GLatLng(53.558584,-7.987061), 6); 
                         map.addControl(new GLargeMapControl()); 
                         var marker = null; 
                         GEvent.addListener(map,"click",function(overlay,point){mapclick 
 (overlay,point)}); 
                 } 
     } 
 
    //]]> 
 </script>

If you can't even get a marker to show up, then you should perhaps take a simple example (Google Maps API Examples - Google Maps API - Google Code) and adapt it.

Got it sorted, got a reply from someone on the gmaps api community.

So what was the problem/solution in the end?
