How do I count the number of unique Event subjects?

Hi everyone,

I need to create an Event report that counts the total number of unique events. The report currently counts the number of people assigned to the event. So if an event has 4 participants, the report counts that as 4 events. I added a power of one field to Events and put it on the report, but it also counts the number of people assigned to the event. Does anyone know how to do this?

Thanks,
