Why is my custom marker not displaying in Google Maps?

Question

Wonder if anyone can help me, the map displays fine but the marker does.

    <script type="text/javascript" src="http://maps.google.com/maps?file=api&amp;amp;v=2&amp;amp;sensor=false&amp;amp;key=ABQIAAAAIoLIQYVphLGoM1pKOrQx0RSlCk5zF9psbOtT7Cn7bdX8qwZsZBTDgtPCGxlAzv6RxAThsHj0CmmZVg"&gt;&lt;/script&gt;
    <script type="text/javascript">

You're not adding any markers to the map - unless you didn't post all of your code here. You'll need to do something like this:

var latlng = new GLatLng(169.132892,-44.698667);
var marker = new GMarker(latlng, {icon:myIcon, title:"dsfsdfljsldk"});
map.addOverlay(marker);
