Portal sub-total rows?
I'm new to this, so please forgive any oversights.
I have a portal in which I would like to insert 'empty' lines that would hold sub-totals; I've arranged a 'manual sort' script that would allow me to put them in any order. What I would like to do is 'accumulate' the amounts (row totals) until that sub-total 'empty' line (detected by its unique ID) that would reset the counter to zero for the next rows down (until the next 'empty' placeholder).
This would be possible if I could carry the line total from one record (row) down to a field in the next (for recalculation), but I can't seem to find any feasible means of doing so.
Thanks for any advice,
