Answer 1

GLatLng takes two numbers as arguments, not a string. You need to do

var centerlat = 1;
var centerlng = 103.849;
map.setCenter(new GLatLng(centerlat,centerlng), 5);

I’m not sure what +Locations+ is designed to achieve. It’s a syntax error. Just use the map.addOverlay() line you had before.

map.addOverlay(new ELabel(new GLatLng(centerlat,centerlng), 2, 'style11'));

Note that Version 2 is deprecated and doesn’t have long to live. Use Version 3 of the API (which is rather different).
