VBA - "Can't Find Project Or Library"

Hi,
I have some moderate knowledge of VBA - not great tho!

I am trying to fix something for a colleague.
At this moment, I cannot upload the sheet onto EE.

Someone send me a workbook.

When I try to compile to VBA I get "Can't find project or Library".

This line is the problem!
NM = MsgBox("Data has been clear", vbOKOnly, "New Month")

There appear to be no other reference in the VBA to "NM".



Sub NewMonth()
    Application.ScreenUpdating = False
    Sheet48.Select
    Range("GoTo1").Select
    Range(Selection, Selection.End(xlDown)).Select
    Selection.Copy
    Range(Selection, Selection.End(xlToLeft)).Select
    Selection.PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone, _
        SkipBlanks:=False, Transpose:=False
    Range("A1").Select
    Sheet38.Select
    Range("EvaDailyData").Select
    Selection.ClearContents
    Range("A1").Select
    Sheet29.Select
    Application.ScreenUpdating = True
    NM = MsgBox("Data has been clear", vbOKOnly, "New Month")
End Sub
