Dear Sir,

Did you try any of that before asking that question?

As far as I am concerned, I do not provide free consulting services. I have spent a lot of time writing an extensive documentation and tutorials, and I believe that if you took the time to read them, you could achieve what you want.

With that said, I leave this thread open is someone else is willing to help you.

Regards

Thanks!
