New to Excel Forum. Working on timed autosave worksheets.

Found a nice post about exactly what to do but when I save the workbook, I get compiler error.

I placed this in the Workbook section:

Private Sub Workbook_Open()

    StartTimer

   End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)

    StopTimer

End Sub

and this in the General:

Option Explicit
Public RunTime
Sub StartTimer()
    RunTime = Now + #12:05:00 AM#
    Application.OnTime RunTime, "SaveBook", schedule:=True
End Sub

Sub SaveBook()
    ActiveWorkbook.Save
    StartTimer
End Sub

Sub StopTimer()
    On Error Resume Next
    Application.OnTime RunTime, "SaveBook", schedule:=False
End Sub

When I save the workbook, I get a highlight on StartTimer in the Private Sub Workbook_Open() and it says Compile error:
Sub or Function not defined

Any help would be appreciated.
