Ok, so the Employee Name in the Calendar Object is a reference attribute to the Employee object. When I put in the rule you mentioned the Appointment.EmployeeName shows up as null. I've found if I put a list of Employee Initials there, plain text attribute, then the rule works and it shows the employee's initials:subject. Is there away around this so I can still use the reference attribute and allow multiples?
Also, I'd like to be able to assign color to each employees appointments - is this possible?
Thanks,
Stef
