Argument 3 in CALCULATE function is required - syntax error?

[kky1]

Hello community - I am getting the error "Argument 3 in CALCULATE function is required for this DAX measure. Reading other posts, most of these appear to be a syntax such  as an extra comma but I am having trouble spotting it in my code. Can anyone assist?

Gender All or selectedInstitutiton_v2: = //used table and measures so there is space between bars on bar charts

//need this so that bar chart retains percentage when only 1 gender selected

VAR __selectedID  = SELECTEDVALUE('parameterInstitution'[shortDisplayName])  

RETURN

IF (

    __selectedID = 'parameterInstitution'[SlicerSelection] && __selectedID in VALUES('Dim_Institutions'[shortDisplayName]),

VAR __selectedUnitID =

CALCULATE(

    MAX('Faculty IPEDS Diversity'[UNITID]),

     'Dim_Institutions'[shortDisplayName] = __selectedID

)

VAR __selected_gender_sel =

CALCULATE(

    SUM('Faculty IPEDS Diversity'[Count]),

    'Peer Groups'[UnitID]=__selectedUnitID, //variable selectedInstitution

)

VAR __all_sel=

CALCULATE(

    SUM('Faculty IPEDS Diversity'[Count]),

    'Peer Groups'[UnitID]=__selectedUnitID, //variable selectedInstitution

    ALL('Faculty IPEDS Diversity'[Sex])

)

VAR __psu=

DIVIDE(

    __selected_gender_sel, __all_sel

)

VAR __selected_gender_all =

CALCULATE(

    SUM('Faculty IPEDS Diversity'[Count])

)

VAR __allgender=

CALCULATE(

    SUM('Faculty IPEDS Diversity'[Count]),

    ALL('Faculty IPEDS Diversity'[Sex])

)

VAR __all=

DIVIDE(

    __selected_gender_all, __allgender

)

VAR __selection=

SELECTEDVALUE('PSU/All Slicer Table'[Sort])

RETURN

SWITCH(

    TRUE(),

    __selection = 1, __psu,

    __selection = 2, __all

))

Thank you @kky1

@kky1 , remove comma in this

VAR __selected_gender_sel =
CALCULATE(
SUM('Faculty IPEDS Diversity'[Count]),
'Peer Groups'[UnitID]=__selectedUnitID, //variable selectedInstitution
)

like

VAR __selected_gender_sel =
CALCULATE(
SUM('Faculty IPEDS Diversity'[Count]),
'Peer Groups'[UnitID]=__selectedUnitID //variable selectedInstitution
)
