This is a formula I wouldn't typically struggle with but I am having experiencing formula block right now...
I am creating a sheet where new lines of data are entered for a test that is run. The unique identifier is the "batch number" and multiple lines of data may have the same "batch number" as tests are run until the product is in spec or is no longer changing. I have added 2 columns to support data management here. The first is "Last Sample" a checkbox manually checked once the last sample has been identified. The second, is "Remove from Report" a checkbox column that would house the formula that checks all tests run for the same batch number to see if Last Sample has been checked. If yes, then it checks last sample and I can use that column to remove all samples from a particular batch from a report.
Happy to provide screenshots if necessary for clarification.
