Nested If Statement

[Anonymous]

The DAX measure code below returns the engagement count and also term and year.  I only want the selected term to show for example "Fall", but I get both Fall and Spring as shown below.

If I remove one If statement and run for either "Fall" or "Spring", I generate the correct ouput.

I am sure the issue is with the commas, but I am not sure how to make this an (If, Yes, No) statement.  

I greatly appreeciate your assistance with t his formatting issue.

VAR _program = Enrollment[ProgramSelection]

VAR _termyear = Enrollment[TermYearSelection]

VAR _intdate = (Int(Right(Enrollment[AYYearSelection],4)))

VAR _sterm = LEFT(SELECTEDVALUE(Enrollment[Start Term and Year]),2)

VAR _enddate = SWITCH(_intdate,

                    2024, TODAY(),

                    2023, TODAY(),

                    2022,  EDATE(TODAY(), -12),

                    2021,  EDATE(TODAY(), -24),

                    2020,  EDATE(TODAY(), -36),

                    2019,  EDATE(TODAY(), -48)

                  )

VAR _count1 =   IF( _sterm = "Fa",                

                        CALCULATE(COUNTROWS(Enrollment),

                         Enrollment[Program] = _program,

                         Enrollment[Start Term and Year] = _termyear,

                         Enrollment[Deposit Intent to Enroll] = "Yes",

                         Enrollment[TermName] = SELECTEDVALUE(FallFilter[Term])),

                IF( _sterm = "Sp",                

                        CALCULATE(COUNTROWS(Enrollment),

                         Enrollment[Program] = _program,

                         Enrollment[Start Term and Year] = _termyear,

                         Enrollment[Deposit Intent to Enroll] = "Yes",

                         Enrollment[TermName] = SELECTEDVALUE(SpringFilter[Term])))        

)

RETURN

_count1

@Anonymous Try using SWITCH instead of nested IF statements.
