Someone on another group graciously supplied this macro to me this
morning. It deposits the date and time into a cell and flashes up a message
box warning the user if it is after time X (in this case, 12 noon). My problem
is that, while the macro runs and deposits the time into the active cell just
great, the message box does not appear. (At the time I ran the tests, it was
already past noon.)

Since I'm running this in Excel X for mac, I thought perhaps someone here
might know of a mac issue that's keepiing this from working all the way.
Thank you!

Sub NewDateAndTime()

Dim mPrompt As String
Dim mBoxStyle As Long
Dim mTitle As String
Dim mMsg As Variant

mPrompt = "It's past 12:00 PM!"
mBoxStyle = 16 ' vbCritical
mTitle = "Warning!"

With ActiveCell

.Value = Now
.NumberFormat = "mm/dd/yy h:mm AM/PM"

If Now Mod 1 12 / 24 Then ' 12/24 = 12:00 PM
mMsg = MsgBox(mPrompt, mBoxStyle, mTitle)
.ClearContents
End If

End With
