None of that is runnable by anyone else.  If you want help, please make 
an effort to be considerate of the people who are trying to help you.

  - Don't post in HTML.  Those asterisks make your code unusable.

  - Do post self-contained examples.  Even if I spent the time to edit 
your post into something I could run, it would fail, because I don't 
have copies of all the variables it uses.
