I'm in a healthcare setting. I'm writing a report to determine 1)how many patients show for their appointments and 2)how many are seen without an appointment. This info comes from two separate tables linked by patient ID. My parameter is a date range. Ideally, I'd like to use the parameter:
({appointment.date} in {?Start Date} to {?End Date}) or
({billing.date} in {?Start Date} to {?End Date})
I've tried several different ways but can't get it to work. Any help appreciated.
