Multiple vba in one sheet

[aikia]

Hello. New to VBA but have seen other threads that say it is not possible to just copy and paste multiple codes into one sheet. Can someone help me merge these two codes below...thank you in advance!

Private Sub Worksheet_Change(ByVal Target As Range)


' To allow multiple selections in a Drop Down List in Excel (without repetition)
Dim Oldvalue As String
Dim Newvalue As String
Application.EnableEvents = True
On Error GoTo Exitsub
If Target.Column = 10 Then
  If Target.SpecialCells(xlCellTypeAllValidation) Is Nothing Then
    GoTo Exitsub
  Else: If Target.Value = "" Then GoTo Exitsub Else
    Application.EnableEvents = False
    Newvalue = Target.Value
    Application.Undo
    Oldvalue = Target.Value
      If Oldvalue = "" Then
        Target.Value = Newvalue
      Else
        If InStr(1, Oldvalue, Newvalue) = 0 Then
            Target.Value = Oldvalue & vbNewLine & Newvalue
      Else:
        Target.Value = Oldvalue
      End If
    End If
  End If
End If
Application.EnableEvents = True
Exitsub:
Application.EnableEvents = True
End Sub

AND

Private Sub Worksheet_Change(ByVal Target As Range)

' To allow dependent cell to become blank if other cell is changed
On Error Resume Next
If Target.Column = 9 Then
  If Target.Validation.Type = 3 Then
   Application.EnableEvents = False
   Target.Offset(0, 1).ClearContents
  End If
End If


End Sub

Welcome to the MrExcel board!

When posting code, please use code tags to preserve the indentation formatting. My signature block below shows you how. I've added them for you above.

No, you can't have two procedures like that, but you can combine them into 1 using a structure like this

Private Sub Worksheet_Change(ByVal Target As Range)
  'Dim all your variables
  
  If Target.Column = 10 Then
    'First code here
  
  
  ElseIf Target.Column = 9 Then
    'Second code here
  
  End If
End Sub
