I don't understand your question and I doubt that anyone else reading
this does either.  As I say at

  "If you do not provide enough information to reproduce the problem
   on my own computer, there will be little I can do to help you. ...
   You should send along a project file, a data file, a screenshot --
   something that helps to explain your problem."

Please read that web page carefully.

This question is also answered at that web page.
