Conditional count for a category column

[xliu1]

I am very new to Power BI. I try to do a conditional count for a category column, and here is my syntax. COURSE_MODALITY is the table, and GRADE_AWARDED is the column. I want to count number of grades in all those categories. I get this error message: too many arguements were passed to the RELATED function. The maximum argument count for the function is 1. How should I modify the syntax? Thanks!

DF Grades = COUNTAX(FILTER(COURSE_MODALITY,RELATED([GRADE_AWARDED] IN {"D","D+","D-","F","U"},)))

Hi @xliu1 

DF Grades = calculate(COUNT(COURSE_MODALITY[GRADE_AWARDED]),COURSE_MODALITY[GRADE_AWARDED] IN {"D","D+","D-","F","U"})

@xliu1 , try like

DF Grades = COUNTAX(FILTER(COURSE_MODALITY,RELATED([GRADE_AWARDED]) IN {"D","D+","D-","F","U"}))

or

DF Grades = countrows(FILTER(COURSE_MODALITY,RELATED([GRADE_AWARDED]) IN {"D","D+","D-","F","U"}))

Hi @amitchandak thanks for your prompt response. I tried both syntaxes. The first one still gives me the same error message. The 2nd one gives me the message: function RELATED expects a fully qualified column reference as its argument. Any idea? Thanks!
