I'm trying to make a form to distribute all the biopsies through the pathologist (residents and assistants), and I need to add two fields which I'm not able to find out how. The first field I need is one in which I see the sum of cases of each pathologist for the day, updated every new biopsy is added. The second field is one in each I can see the pathologist who received prostate biopsies in the previous day.

Can anyone help me?
