VBA Excel how to activate macro for sheet 2, 3 and 4 from sheet 1

Question

I have 3 workbooks in one folder.
I use macro to copy each Sheet1 in every workbook in that folder into my workbook example .
In my workbook example now I have 4 sheets named sheet1 , sheet1 (4), sheet1 (3), sheet1 (2).

I want to use a button form so when I click it, the code (below) run for any other sheets except sheet one.

Sub Copy_Sum()
    Dim ws As Worksheet
    'Selecting the worksheets to loop through
    K = 1
    For Each ws In ThisWorkbook.Worksheets
    'Skiping the sheet1
        If ws.Name <> "Sheet1" Then
    'Counting the number of rows for automation
            rowscount = Cells(Rows.Count, 1).End(xlUp).Row
            temp = 0
    'add name
            Cells(rowscount + 1, 8) = "Jumlah"
            Cells(rowscount + 2, 8) = "Mutasi"
    'Looping throught the cells for the calculation
            For j = 2 To (rowscount)
               'Counting the number of cells which value greater than zero
                If Cells(j, 9) > 0 Then
                    temp = temp + 1
                End If
            Next j
    'Counting the number of rows for automation
            rowscount1 = Cells(Rows.Count, 1).End(xlUp).Row
            temp1 = 0
            For i = 2 To (rowscount1)
            'Counting the number of cells which value greater than zero
                If Cells(i, 10) > 0 Then
                    temp1 = temp1 + 1
                End If
            Next i
     'Summing up the values which are above the current cell
     'and in Sheet1, this inclues negative numbers as well
            Cells(rowscount + 1, 9).Value = Application.Sum(Range(Cells(1, 9), _
                Cells(rowscount, 9)))
            Cells(rowscount + 2, 9) = temp
            Cells(rowscount1 + 1, 10).Value = Application.Sum(Range(Cells(1, 10), _
                Cells(rowscount1, 10)))
            Cells(rowscount1 + 2, 10) = temp1
        End If
    Next ws
End Sub

I'm don't fully understand the macro code.
This code was made by editing the code from NEOmen and I really appreciate it.
This is code supposed to automatically loop the code for each sheet except sheet1 but it didn't work.
I must run the code manually in sheet1 (4), sheet1 (3), sheet1 (2) to get it done.
I think I can edit it a little bit like what I wanted, but I can't.
I got stuck in the end.

the code after revision from @chris neilsen @L42

Sub Copy_Sum()

Dim ws As Worksheet

        .Cells(rowscount + 1, 8) = "Jumlah"
        .Cells(rowscount + 2, 8) = "Mutasi"

             .Cells(rowscount1 + 2, 10) = temp1
             'copy ke sheet 1

             End If
    End With
Next ws

End Sub

Answer 1

The problem is you're not referencing the object correctly.
Try fully qualifying your objects by using With Statement .

For Each ws In Thisworkbook.Worksheets
    With ws 'add With statement to explicitly reference ws object
        'precede all properties with a dot from here on
        If .Name <> "Sheet1" Then
            rowscount = .Cells(.Rows.Count, 1).End(xlUp).Row 'notice the dots
            temp = 0
            '~~> do the same with the rest of the code

        End If
    End With
Next
