Pass custom fields values to Google Maps

Hi all,

I am using this script to display google maps on my wordpress site:

 <head>
<script>
function initialize()
{
var mapProp = {
  center:new google.maps.LatLng(51.508742,-0.120850),
  zoom:5,
  mapTypeId:google.maps.MapTypeId.ROADMAP
  };
var map=new google.maps.Map(document.getElementById("googleMap")
  ,mapProp);
}

google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>

I have set up two custom fields “fl_long” , “fl_lat” for the longitude and latitude.

How do I modify the code above so that the values are taken from the custom fields instead of being hardcoded numbers?

ok found the answer please ignore - it’s quite easy to insert between <?php > tags
