I have use following code for this and i use input box for variable criteria(i) center.

Code:

Sub mcopy()
Call DeleteRowsBelow
a = Worksheets("CRM").Cells(Rows.Count, 1).End(xlUp).Row

Dim myModule As String
myModule = Application.InputBox("Enter a Module")

For i = 2 To a
    If Worksheets("CRM").Cells(i, 4).Value = myModule Then

        Worksheets("CRM").Rows(i).Copy
        Worksheets("MODCRM").Activate
        b = Worksheets("MODCRM").Cells(Rows.Count, 1).End(xlUp).Row
       
        Worksheets("MODCRM").Cells(b + 1, 1).Select
        ActiveSheet.Paste
        Worksheets("CRM").Activate
    End If
Next

Application.CutCopyMode = False
'ThisWorkbook.Worksheets("CRM").Cells(1, 1).Select

End Sub

Sub DeleteRowsBelow()
    Worksheets("MODCRM").Rows(3 & ":" & Worksheets("MODCRM").Rows.Count).Delete
End Sub
