Hello, i have a report that has "unit #", "date of maintenance", and "mileage". what i want the report to do is forcast the next time vehichles will need serviced. i want to simply add 3000 to the miles control. i've tried doing this everyway i can think of but nothing works. i will then need the same thing with the date. when i do this i usually get a #name? error. could someone please show me how to do this. any help would be great. thanks.
