Should I put that bit of code at the top of the macro, below, the opening, like this:

Sub emptyUnlocked()
If Target.Cells.Count > 1 Then Exit Sub
   If MsgBox("Are you sure ?", vbYesNo + vbQuestion) = vbNo Then
   Exit Sub
Doing it that way gets me a Run-time error 404 "Object required"

Also, do you know of a safer, better way to clear the data input/unlocked cells in my calendar?

Thanks so very much
