This works. However I may need some additional help.
Is there a way do this without the helper columns? My final goal is to be able to calculate the remaining PO Balance amounts based on the code, service type, and budget year. Similar to the formulas that are in D65:D69.
Thanks for your time and help, it is appreciated.
