Sumifs in Excel-VBA

Question

I have some problem with sumifs in vba:

Dim Arg1 As Range 'the range i want to sum
Dim Arg2 As Range 'criteria range
Dim Arg3 As Variant 'the criteria

Set Arg1 = ThisWB.Sheets("Sheet1").Range("B2:B100")
Set Arg2 = ThisWB.Sheets("Sheet1").Range("C1:C100")
Set Arg3 = ThisWB.Sheets("Sheet2").Range("A2:A12")

For i = 2 To 12
Workbooks("x.xlsx").Worksheets("Sheet2").Cells(i, LastColumn) _
= Application.WorksheetFunction.SumIfs(Arg1, Arg2, Arg3)


Next

I always get a "Type mismatch" error

Could anybody help me to fix the code?

Thank you in advance.

Sub test()
    Dim Arg1 As Range 'the range i want to sum
    Dim Arg2 As Range 'criteria range
    Dim Arg3 As Variant 'the criteria

    'Arg1 and Arg2 must be the same size
    Set Arg1 = Sheets("Sheet1").Range("B2:B100")
    Set Arg2 = Sheets("Sheet1").Range("C2:C100")

    'this is the criteria
    Arg3 = "=False"

    Dim ws As Worksheet
    Set ws = ActiveSheet
    Dim i As Integer
    For i = 2 To 12
        ws.Cells(i, 8).Value = Application.WorksheetFunction.SumIfs(Arg1, Arg2, Arg3)
    Next
End Sub

You can also specify Arg3 as a variant and pass a single-cell range if it has the criteria. Criteria can be True/False (=False), a number (20) or a string (">100").

    Dim Arg3 As Variant 'the criteria
    Arg3 = Sheets("Sheet2").Range("A2")

EDIT: I realized what you were trying to do. Each cell in Arg3 is a separate criteria that you want to do SumIf on. Here is the revised code.

Sub test2()
    Dim ThisWB As Workbook: Set ThisWB = ThisWorkbook
    Dim i As Integer
    Dim LastColumn As Integer: LastColumn = 3

    Dim Arg1 As Range 'the range i want to sum
    Dim Arg2 As Range 'criteria range
    Dim Arg3 As Range 'the criteria (range)

    Set Arg1 = ThisWB.Sheets("Sheet1").Range("B2:B100")
    Set Arg2 = ThisWB.Sheets("Sheet1").Range("C2:C100")
    Set Arg3 = ThisWB.Sheets("Sheet2").Range("A2:A12")

    For i = 2 To 12
        Workbooks("x.xlsx").Worksheets("Sheet2").Cells(i, LastColumn) _
            = Application.WorksheetFunction.SumIfs(Arg1, Arg2, Arg3.Cells(i - 1, 1).Value)
    Next
End Sub

Note how Arg3 is used in SumIfs Arg3.Cells(i - 1, 1).Value. Also note that Arg1 and Arg2 must be the same size.
