The problem this user faces isn't a formula error; it's a logic gap. When SUMIFS returns zero despite visible data, the issue almost always lives in the criteria ranges, not the math. The user has a table with Date, region, product, and Revenue columns, and they want a single formula that sums revenue for a chosen region, product, and date range. Dynamic arrays make this elegantly simple, but only if you understand how the function evaluates each condition.
Let's walk through the likely cause of the zero. If you typed dates into cells H4 and H5, Excel might store them as text strings instead of serial numbers. SUMIFS compares exact values, so a text date never matches a numeric date in the table. The fix is to wrap the date criteria in the DATEVALUE function, or better yet, use actual Excel dates by typing them with the DATE function. Another common mistake is referencing the entire table column for the sum range but using mismatched row counts in the criteria ranges. With dynamic arrays, you can use structured references like `Table1[Revenue]` for the sum range and `Table1[Region]` for the criteria range, but ensure every range is the same size. If you used a mix of full-column references and table column references, the mismatch forces a zero result.
The practical solution is a single FILTER function wrapped in SUM. Write `=SUM(FILTER(Table1[Revenue], (Table1[Region]=H2)*(Table1[Product]=H3)*(Table1[Date]>=H4)*(Table1[Date]<=H5)))`. This formula filters the Revenue column to only the rows where all four conditions are true, then sums the result. It is precise, readable, and requires no helper columns. If you still get zero, check that H2 and H3 contain exact matches, no extra spaces. Check that H4 and H5 are actual date values, not text. Check that your table's Date column is formatted as a date, not as text. Those three checks will resolve nearly every case.
This is what progressive data management looks like. You don't need pivot tables or VBA to answer a straightforward business question. You need a formula that thinks in arrays, not cells. The FILTER function, combined with multiplication logic for AND conditions, gives you that power. Stop fighting with SUMIFS quirks. Start using the tools that treat your data as a connected whole, not a grid of isolated cells.
