Okay, I finally got this working the way I needed. As this project grows I will need to "copy sections" down for additional data. The gray row is for a parent, and the white are the child rows.
The column labeled "Auto" uses the Auto number format. But for the life of me, I do not understand WHY I cannot copy down sections and then the Auto numbering SHOULD update in the correct sequence. It appears the ID & Parent columns are only off because the Auto Number is off. Why is this and how do I fix it?
