I'm wondering if its possible to create a specific expression in a group header. My records all have a field called [Temperature]. In a report I'd like to have group headers that show/group all records where [Temperature] falls between two values. In other words show all records where the [Temperature] is between 90 and 75 in one header and between 74 and 50 in a second header and between 49 and 30 in the last header. Is this possible?
