Hi Giri, thanks for responding. Below is an example of the database. These are some of the fields, at least the ones that are important. There are no references between fields. The collection is called “Song Critiques”.
In this example, there are nine critiques given by five different people. I already have a page that counts the number of songs and the number of critiques. What I am trying to do is count how many different people critiqued a song, five in this case. Sorting allows me to group the "critiquers " together but not add up how many different people have critiqued. Let me know if you need more info. I would be grateful for any help.
