I've nudged OP's via comment to take the question off the "unanswered list" by accepting an answer, stating what is not working with an answer (so it can be amended with improvements) or posting their own answer. Who's answer is accepted is a moot point because the important thing is to take the question off the unanswered list.

Of course our egos all want our answer to be the accepted one but the right thing is for the right answer to be accepted. Occasionally based on OP comments you have to badger them to write their own answer.
