Hi @chay . Your image is too small to read anything. If you can attach the Excel file, it would be easier to help. I don't think you'll want to be using a formula though since you are comparing the value of one record to other records. I can see several different ways this might be done (summarize tools and joins, multirow formulas, etc.), but I need to know more about your data first.
