I am trying to create a simple Attendance "Punch Card" type app.

I have two forms.   Student and Attendance.   I have a bi-directional lookup between them that is working.   In Attendance you can select students for a date.   In Students it shows the dates they are present.

I have figured out the Workflow scripting to get a field in Students on Form Load to show total number of Attendance presents.  input.Total_Classes_Taken = input.Attendance_Date.size();

But I do not want to open each student to see how many classes they have taken.  I have not been able to figure out how to get this number to show up in a Student Report.
