If Or Statement not functioning correctly

hi guys,

I'm using the following If Or statement to only proceed if integer iCol <> 1, 2 or 3

If iCol <> 1 Or iCol <> 2 Or iCol <> 3 Then
  Cells(iRow + 5, iCol).Value = "Feedback:"
End If

however this still isnt working correctly, i was wondering as to the reasons why this is happening?

Thanks
Kind Regards
Jordan
