How to use OR condition to add another target cell?

With Intersect(Target,cells(i,j) only, the code works fine but adding another statement after OR throws an error saying object or with block variable not set.

Objective: throw a prompt, for copy and paste, at row 86 and row 70 using worksheet event function.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

Dim j As Integer

j = ActiveCell.Column 'basing off activecell made it dynamic

Debug.Print j

If j > 2 Then 'must be more than column b


     If Not Intersect(Target, Cells(70, j)) Or Intersect(Target, Cells(86, j)) Is Nothing Then 'there is something
          'add a column or not
          addCol = MsgBox("You have reached a mandatory field. Would you like to add another project?", vbYesNo + vbQuestion)
          
          If addCol = vbYes Then
               Columns(j).Copy (Cells(1, j + 1))
               Cells(71, j).Activate 'go to next row within same project column
               Cells(2, j + 1).Value = "Input " & (j - 2)
          Else
               MsgBox "You have decided NOT to add another project!", vbInformation
          End If
     End If
     
Else
     Exit Sub
     
End If

End Sub
