Issues using measure in a summarize

[Anonymous]

Hello

I’ve have a student db. Students can be scheduled to take exams, but exams can be rescheduled, which adds another record. I’ve got the measure below, that counts the scheduled exams based on the maximum ExamBooked_Date

The number being returned is correct, but if I pull in the ExamBooked_Date, the report displays all the booked dates when I want to display only the Max(ExamBooked_Date)

How do I adjust the measure to surface only the Max(ExamBooked_Date), or do I need an additional measure just to do this?

m_Exam_Booked:= COUNTROWS (

        FILTER (

            SUMMARIZE (

                tblExams,

                tblExams[StudentId],

                tblExams[ExamName],

                "Max Planned Exam Date", MAX ( tblExams[ExamBooked_Date] )

            ),            tblExams[ExamName] = "English Level 2"       )

Thanks in advance
