Obviously a continueation of this thread:http://www.dreaminco...1&#entry1831457
Your question is pretty much "can anyone give me the code to do this".
We're not going to write your homework for you, or give you code for your homework.
You tried: That's good.
You got errors: That can be addressed.
What code did you try and what were the errors?

Does not help us, to help you. Specifically show us the code you are using and the errors you got.
