I'm trying to convert our commonly used pivot tables into formulas based static tables. I've made great use of DSUM for most of them, put I'm not sure if this is an option for this one.
I've attached a sample of the spreadsheet I'm working with. I need it to search for the specified Area, Account and Month, and then give me a list of companies and their subcategories, and add together the totals for them. My problem is that I don't know what companies will be used each time. I can build a list of commonly used ones, but that won't help if one month we use an oddball one. Pivot tables aren't an option because size is an issue.
