Actionscript for fms

I want to create a live chat between two people.I use hosting a company. I created an application called mytestone. I have edited the main asc file. I think i typed everything in correctly maybe my rtmp url is incorrect? Because i went into my admin console and clicked connect and nothing appeared.
Anyway, i have copy and pasted my asc file below: I am new to actionscript so please tell me if i made any errors.

var nc.connect("NetConnection = new NetConnection();
nc.connect(“rtmp://fmsserver272.rtmphost.com/mytestone”);
//setup the camera and mic for streaming
mycam = Camera.get();
mycam_audio = Microphone.get();
//control the cameras mode and quality
mycam.setMode(320,240,30);
mycam.setQuality(10000,100);
//attach a vlive preview of the camera to the
//video object that is setup on the stage
cam_feed.attachVideo(mycam);
cam_feed.attachAudio(mycam_audio);
//connect to the Flash Media Server
client_nc = new NetConnection();
client_nc.connect(“rtmp://fmsserver.rtmphost.com/mytestone”);
cam_ns = new NetStream(client_nc);
//attach our camera video and audio to the net stream
cam_ns.attachVideo(mycam);
cam_ns.attachAudio(mycam_audio);
//publish to our Flash Media Server as a
//live stream called user_1
cam_ns.publish(“user_1”, “live”);
//bring in user_2’s video/audio
in_ns = new NetStream(client_nc);
