You are welcome. Yes threading means something like that - when it is started off. It does not matter if you can spell or not, there is always a dictionary, thesaurus and in the software there is usually a spellchecker. What I appreciated from you was your willingness to help someone in need and having the experience and/or ability to help and give it freely. In forums like this, it's what counts. Not a rebuff or sarcastic answer. Thank you for being a sharing human being.All the best to you.
