I did indeed close this question. It had been tagged "DoIt4Me" and there was already a comment stating it was unclear. I agreed.
The purpose of closing is to avoid attracting answerer's time on questions that are not clear. I am not sure how to deal with the situation where someone is working off-line on a question that is marginal like this one was at the time I closed it.
It really looks to me like the questioner modified the question (as requested), so the system mostly worked.
There was reasoning sent to the questioner. IT is not public, but maybe it should be. I do not close questions that have answers in place.
