State Boundaries (polygons) via KML files??

I know this is not a feature of Pro Maps but I have been trying to hand code this into the completed map. Has anyone been successful in doing this?

I need to highlight a couple of states on a US map that currently has markers fed from a recordset.

The KML file was generated using Google Earth and saved out.
I then uploaded the .kml file to a server. But adding it in as a new layer just isn't working for me.

At google's site on the subject they give you this code, which includes too much information since the map and centering code is there too. So I tried commenting parts out and then updating the element id for my map and the path to the kml file on my server.

function load() 
{
  var map;
  var geoXml;

  if (GBrowserIsCompatible()) 
  {
    map = new GMap2(document.getElementById('map'));
    map.addControl(new GSmallMapControl());
    map.addControl(new GMapTypeControl());
    geoXml = new GGeoXml('http://example.com/phpmysql_kmlnl.kml');
    map.addOverlay(geoXml);
    map.setCenter(new GLatLng(47.613976,-122.345467), 13);
  }
}

I've tried to incorporate it into the current Pro Maps javascript but it's being ignored.
Attached is the KML file I am using which should be putting a red overlay over Pennsylvania.

My guess is that I am not setting the variable for the new geoXml layer correctly.

Any help would be appreciated.

Thanks,
