Merge workbooks - take other values ​and add them to column C - excel

Question

This is a piece of code that takes some values ​​(A1: C5) and pastes them, one below the other, in column B. Obviously, in column A there is the name of the file.
Now, simply, I need to take another content piece (B2: D13) and insert it in column C.
I tried but it doesn't stick anything to me.

Dim BaseWks As Worksheet
Dim rnum As Long
Dim CalcMode As Long
Dim MySplit As Variant
Dim FileInMyFiles As Long
Dim Mybook As Workbook
Dim sourceRange As Range
Dim destrange As Range
Dim SourceRcount As Long
'Add a new workbook with one sheet
Set BaseWks = Workbooks.Add(xlWBATWorksheet).Worksheets(1)
BaseWks.Range("A1").Font.Size = 36
BaseWks.Range("A1").Value = "Please Wait"
rnum = 3
'Change ScreenUpdating, Calculation and EnableEvents
With Application
CalcMode = .Calculation
.Calculation = xlCalculationManual
.ScreenUpdating = False
.EnableEvents = False
End With
'Clear MyFiles to be sure that it not return old info if no files are found
MyFiles = ""
'Get the files, set the level of folders and extension in the code line below
Call GetFilesOnMacWithOrWithoutSubfolders(Level:=1, ExtChoice:=0, FileFilterOption:=0, FileNameFilterStr:="")

'FileFilterOption : 0=No Filter, 1=Begins, 2=Ends, 3=Contains
'FileNameFilterStr : Search string used when FileFilterOption = 1, 2 or 3
' Work with the files if MyFiles is not empty.
If MyFiles <> "" Then
MySplit = Split(MyFiles, Chr(13))
For FileInMyFiles = LBound(MySplit) To UBound(MySplit)
Set Mybook = Nothing

Untested but should be more or less OK:
Sub MergeCode1()
Dim BaseWks As Worksheet
Dim rnum As Long
Dim MySplit As Variant
Dim Mybook As Workbook
Dim src1 As Range, src2 As Range
Dim destrange As Range
Dim Rcount As Long
Dim f
'Add a new workbook with one sheet
Set BaseWks = Workbooks.Add(xlWBATWorksheet).Worksheets(1)
BaseWks.Range("A1").Font.Size = 36
BaseWks.Range("A1").Value = "Please Wait"
rnum = 3
MyFiles = ""
Call GetFilesOnMacWithOrWithoutSubfolders(Level:=1, ExtChoice:=0, _
FileFilterOption:=0, FileNameFilterStr:="")
If MyFiles <> "" Then
MySplit = Split(MyFiles, Chr(13))
For Each f In MySplit
Set Mybook = Workbooks.Open(f)
Set src1 = Mybook.Worksheets(1).Range("A1:C5")
Set src2 = Mybook.Worksheets(1).Range("G8:Z10")
'max # of rows to be added...
Rcount = Application.Max(src1.Rows.Count, src2.Rows.Count)
If rnum + Rcount >= BaseWks.Rows.Count Then
MsgBox "Sorry there are not enough rows in the sheet"
Mybook.Close savechanges:=False
Exit For
Else
BaseWks.Cells(rnum, "A").Resize(Rcount).Value = f
BaseWks.Cells(rnum, "B").Resize(src1.Rows.Count, _
src1.Columns.Count).Value = src1.Value
BaseWks.Cells(rnum, "B").Offset(0, src2.Columns.Count) _
.Resize(src2.Rows.Count, src2.Columns.Count).Value = src2.Value
rnum = rnum + Rcount
End If
Mybook.Close savechanges:=False
Next f
BaseWks.Columns.AutoFit
End If
BaseWks.Range("A1").Value = "Ready"
End Sub
