Copy Cells from multiple workbooks

[Purdue02]

I am using the following code to open multiple workbooks and copy a range of cells into one workbook. It is currently copying B12:D12 and inserting values into A:C. I want to modify the code to just copy B12 & D12 and insert into columns A & B in new worksheet. I would also like to specify in what cell to start inserting values. Any suggestions would be appreciated.

Sub CopyRangeValues()
    Dim basebook As Workbook
    Dim mybook As Workbook
    Dim sourceRange As Range
    Dim destrange As Range
    Dim rnum As Long
    Dim i As Long
    Dim a As Long
    Dim MyPath As String
    Application.ScreenUpdating = False
    With Application.FileSearch
        .NewSearch
        .LookIn = "P:\"
        .SearchSubFolders = False
        .FileType = msoFileTypeExcelWorkbooks
        ChDrive .LookIn
        ChDir .LookIn
        FNames = Dir("*AP AR*.xls")
        If .Execute() > 0 Then
            Set basebook = ThisWorkbook
            rnum = 1
            Do While FNames <> ""
                Set mybook = Workbooks.Open(FNames)
                Set sourceRange = mybook.Worksheets(1).Range("B12:D12")
                a = sourceRange.Rows.Count
                With sourceRange
                    Set destrange = basebook.Worksheets(1).Cells(rnum, 1). _
                                    Resize(.Rows.Count, .Columns.Count)
                End With
                destrange.Value = sourceRange.Value
                mybook.Close False
                rnum = rnum + a
                FNames = Dir()
            Loop
         End If
           
           
    End With
    Application.ScreenUpdating = True
End Sub
