Flash Remoting not working

Ok, so I tried the hello world example below and still can't get it to work. When I use cfinvloke to test it works via web browser.

Here is my Code:

import mx.remoting.*; // I switched to this instead of the old #include in the example.

function Result()
{
//receives data returned from the method
this.onResult = function(result){
trace("Data received from server : " + result);
}

this.onStatus = function(error){
trace("Error : " + error.description);
}
}

NetServices.setDefaultGatewayUrl(" http://localhost:8500/flashservices/gateway");
var gw = NetServices.createGatewayConnection();
var server = gw.getService("com.macromedia.test.HelloWorld", new Result());
server.sayHello();

I am running the CF Sever 7,0,2,142559 on IIS.

I have a the HelloWorld.cfc file in the wwwroot/com/macromedia/test
directory and I am the calling the .swf file after it is published.

When I try to view it through the browser or flash 8 I just get a blank screen.

Can someone please help me with this. I have been working on this all day and am about to throw in the towel. I'm sure this is something simple.

Thanks
Dave
