I have a list of dates when vehicles need to be serviced and I have a list of their reg nos and whether it is PSV, service or MOT. None of these are measurements. I'd like to show a schedule against the columns for months and listed below each month then details of the vehicle.
Caroline welcome to the forums! I was going to be a smart-*** and suggest you put your PSV field on the LOD shelf and make sure the MOT.... But then I saw you are new. So let me suggest that a packaged workbook with sample data goes a long way toward getting a quality answer.
