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): H2:H24 Expected answer sheet(s): Task: First unmerge any merged cells. How can I count the number of unique Item Nos. that have been placed into a Bin and reset this count whenever the items are taken by another department, while also retaining both the initial count and any subsequent counts? The need is to track how many unique items are added to a Bin before it's passed on to the next department without losing the count of items from previous cycles. Need to count the number of unique 'Item No's in E2:E10. Place output in H10. Need to count the number of unique 'Item No's in E11:E20. Place output into H20. Need to count the number of unique 'Item No's in E21:E24. Place the output into H24.
