Ok, one thing i see is there is no range to hide, so try this
Range("B:B,D:D,F:F,H:H,J:J").Select
Put the code above right above the "Selection.EntireColumn.Hidden = True" part in your macro. You will have to replace the "B:B,D:D,F:F,H:H,J:J" with the columns that you want to hide.
So your macro woudl look like this
Sub mintest1()
'
' mintest1 Macro
'
' Keyboard Shortcut: Ctrl+s
Range("B:B,D:D,F:F,H:H,J:J").Select
Selection.EntireColumn.Hidden = True
End Sub
Let me know if it works
