An expense ledger for March and ten questions about it. Each answer goes in column G, one per task. Some need one condition (SUMIF), some several (SUMIFS); some take the condition from a cell (B13 holds a team, D13 a date).
Criteria reminders: text in quotes, a cell without quotes, comparisons in quotes joined to a cell with & (">="&D13), not equal is "<>Sales", and wildcards work on text.
