I think this was explained to you pretty well in the other thread you started on this subject.

This thread should be a reply in that original thread as it is just a continuation of the conversation. There was no need to start another thread.
Go back to the original thread and discuss this, I'm locking this one.
This helps keep things neat and tidy for people looking for answers later.
