I did it. Had a smaaaaaaall but very significiant error. My file reader was not reading well. And subscribe name was different. Now it works and sends data.

Well then, now I have another question. I have to make a graph from data I recieve. It must be in realtime. Can I have your recommendation? Maybe store the recieved data in a buffer or something so I can access it and plot a graph? Mentor suggested I use adobe flex for plotting.
