I have columns Person ("Adam", "Bob", "Charlie"), Day ("Monday",
"Tuesday", etc), Total. I'd like to SUMIF based on BOTH Person and Day
(e.g. sum for "Bob" and "Tuesday"). I'd rather not use PivotTables,
because (1) this is pretty simple and (2) people here are scared of
PivotTables. Can i use SUMIF based on 2 columns, either by
concatenating the text or with an array? Thanks.
