www.dirtybirdsurf.com

the buoy read out on the right hand side should read the current buoy readings through my server php which are then cached on my server from the nooa.gov site
here is the action script

var loader:URLLoader=new URLLoader();
loader.load(new URLRequest(“http://www.dirtybirdsurf.com/proxy.php?url=http%3A//www.ndbc.noaa.gov/data/latest_obs/41035.txt”));
loader.addEventListener(Event.COMPLETE, onComplete);
function onComplete(event:Event):void
{
external_txt.text = event.target.data;
}
