I work for an ambulance company and we have a database that stores information from all of our emergency runs.  In one table it keeps information about the crew that ran the call.  Things like driver name, attendant name, vehicle number, etc.  I need to be able to count the number of trips an individual employee has run.  That Employee's name could be in either column (driver or attendant).  I can't seem to get both totalled under one group heading.
