You are solving a spreadsheet benchmark task in a real workbook. Objective: Produce the correct final workbook state for the expected answer region. What matters: - Only the values in the expected answer region will be graded. - The workbook is the answer. Instructions: 1. Read the workbook and inspect the relevant data region first. 2. Infer the required result for the provided workbook instance. 3. Write the final value(s) directly into the expected answer region. 4. Do not rely on prose, formulas in your chat response, pseudocode, or VBA as the answer unless the benchmark explicitly requires those to be written into cells. 5. If the natural-language task asks for a general method, formula, or macro, convert that into the concrete result needed for this workbook instance. 6. Keep your final text response short and only summarize the workbook cells you changed. Relevant data region(s): Expected answer region(s): 'book1'!B3:B23 Expected answer sheet(s): Task: How can I create a formula in Excel that allows me to sum values across three columns based on a single criterion? I've attempted to use SUMPRODUCT with the formula =SUMPRODUCT(book2!A:A=book1!A3)*book2!H:J, but it seems like there might be a mistake because it isn't functioning as expected. SUMIF does not seem to be an option since the sum range spans multiple columns. What would be the correct formula to achieve this result? My current formula is:SUMPRODUCT(book2!A:A=book1!A3)*book2!H:J
