end of survey - counting

I made survey.
(I explain a bit to make you understand my question.
Through upper some questions, I distinguish whether this person fit to my survey.
so if they don't fit they could not continue.
But I would like to count the person who are fit my question. because I designed randomization question evenly.
but all people are still counting even they are not fit anymore..

I do not want to person who are not fit my question. I want to count and evenly distribute the person who are fit.

then how to set up the question?
