Excel VBA SUMIF Run-time error '424': Object Required

This produces an Error: Run-time error '424': Object Required

Private Function Y_Mode() As Double
    Dim MaxGrad As Double
    MaxGrad = WorksheetFunction.Max(Graduation_Series)
    Y_Mode = WorksheetFunction.SumIf(Graduation_Series, MaxGrad, Y_Series)
End Function

It is failing on this line:

Y_Mode = WorksheetFunction.SumIf(Graduation_Series, MaxGrad, Y_Series)

Everything seems defined and instantiated properly and the elements of each array are of type Variant/Double

Watch : + :     Graduation_Series :  : Variant/Variant(0 to 14) : SU_Solution.Y_Mode
Watch :   :     MaxGrad : 474.281204765715 : Double : SU_Solution.Y_Mode    
Watch : + :     Y_Series :  : Variant/Variant(0 to 14) : SU_Solution.Y_Mode

I tried putting MaxGrad into a Range and then referencing the Range in SUMIF, but that did not work either.

Solution

  • You cannot use SUMIF with arrays.

    The criteria that you can use with the SUMIF() worksheet function is limited to text, numbers, or a range, and the function cannot use array constants.
