I am looking for a vlookup formula where the the table array is the entire workbook, not just a range of cells within a particular worksheet. I also want the vlookup to return a sum of all returned values, not just the first instance.
ie... I ordered ceiling tile #2 on 10/30/10 (cost me $100), 11/4/10 ($100) and 11/12/10 ($200) and I want the vlookup to search the workbook, find every instance that I order ceiling tile #2 and return a value of $400, not just $100.
Is this possible? Thanks in advace.
PS- I'm tryining to create this vlookup in the same workbook, not link to another. I'm using Excel 2007.
