NOT AT ALL! I appreciate the correction - while tone of a statement can be tough to interpret online with folks you do not know, I took it as a genuine interest in getting things right.I chose not to imagine you suffixing it with " you stupid moron of a newbie!"

As a science teacher, I often have to bite my tongue when well meaning people butcher what I think are basic details. I stand corrected and do not feel scolded at all.
