I have a sheet of balances and a sheet of spends. The sheet of balances has a column for each name and a row for each date. The sheet of spends is a list in order of date of each spend with each row indicating a name, date and spend. The list includes a name multiple times (one for every date they spent on). If I want to do calculations based on the data for both balance and spend for each name how would I get excel to understand that when I refer to a name and date in one sheet I also want to refer to that same name and date in the other sheet to take both spend and balance for the name and date. Or is there a quick way to make a new list with both spend and balance for each name and date?
