**PsyDAG**, Saturday, December 18, 2010 at 12:31amFirst, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.

Second, it would be easier for us to help you if you had a specific question or problem.

Repost again on your own.
