Hi! I am looking for some help. I am trying to configure the multi-row formula and run total to copy the calculation form excel, but with no luck. Basically I am trying to calculate when Im going to run out of some items, depending on the demands and qty on in each group. So if column A becomes negative, then i am taking the items from B, if B becomes negative, then I go to D. Hope it makes sense. I would appreciate any help.
