I am using Digital Metaphors' Report Builder for calculating equipment downtime. I would like to count the number of days that a particular machine had downtime occurences. I have the report set up to list the work order, the date of the downtime, the hours, and the reason. It summarizes by totalling the # of work orders and the # of hours for each machine. All I need now is to summarize the number of days that had downtime occurences for a particular machine. I am not a programmer, but I am usually good at following instructions! Anyone out there that can help me?
