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.
