Can't find project or Library error

[Kysteratwork]

Hi all,

I have a question with regards to this code I use in a form to display time and date:

Private Sub Form_Timer()
Me!lblClock.Caption = Format(Now, "dddd, mmm d yyyy, hh:mm AMPM")
End Sub

Private Sub cmdClockStart_Click()
Me.TimerInterval = 1000
End Sub

Private Sub cmdClockEnd_Click()
Me.TimerInterval = 0

End Sub

But I get an error message saying:
"Compile error: Can't find project or library"
And format is higlighted in the code.

What does this mean?
Thank you for any indication you may have.
