My project, I Need Help !! Flash Live Video/Audio Streaming

Hi, I need some help with my project. I created a live Audio/Video streaming function ( two way and four way webcam) using Flash cs3 and Flash Media Server and when I tested the application, it did not work at all. I am sure that I have done everything correctly but for some reason I cannot make the application to show my webcam just to test it!! I need someone( a flash expert ) to have a look at the codes and to see why it doesn't work?!? All the codes are written and ready and all I need is your advise... I don't need any more coding at all. (maybe) Please bid if you only know what you re doing and not just to test your abality. I repeat again, this is a very simple job and I only need your advise.. that's all Thank You Kind Regards
