I have a new field in EventData table (TripDistance) get directly from GPS Tracker (obtained every GPRS data message send to server, only between messages , Ex. 60 Sec, send a 0.452 Km, the next message reset and send the new distance 0.587 Km). This data has stored on new field on EventData table, and all Ok. The Question: How totalizing this field on Event Detail report. The totalizing depend on Date and time set.
Please explain as Step By Step Procedure.
Thanks in Advance
