How to use google maps API with multiple markers on the same map

Question

So, i have the following script to use the google maps API, its all fine, but i need to create a map that has more than one Marker (the balloon shaped icon pointing to something) and i need each of those markers to point on a different area of the map (i.e. different coordinates), how can i do it?

<script type="text/javascript">

         function load() {

        var map = new GMap2(document.getElementById("map"));
        var marker = new GMarker(new GLatLng(<%=coordinates%>));

        var html="<img src='simplemap_logo.jpg' width='20' height='20'/> " +
             "<%=maptitle%><br/>" +
             "<%=text%>";



        map.setCenter(new GLatLng(<%=coordinates%>), <%=zoom%>)
        map.setMapType(G_HYBRID_MAP);
        map.addOverlay(marker);
        map.addControl(new GLargeMapControl());
        map.addControl(new GScaleControl());
        map.addControl(new GMapTypeControl());


        marker.openInfoWindowHtml(html);
        }

        //]]>
        </script>

One more question, if i pass the Script text as a variable, lets say something like:

<script type="text/javascript">
<%=ScriptText%>
</script>

and my <%=ScriptText%> will be a string which i will build and assign its value to a Friend or Public variable called ScriptText, will it still run and work properly? (i am doing this to make my script dynamic and different based on how i build it as a STRING, due to my illiteracy in javascripting ;P)
