Wm,
Unlock all cells that are allowed to have data entered (format / Cells... Protection tab, uncheck
"Locked"). Then use Tools / Protection / Protect Sheet... and turn on sheet protection (with or
without a password - I would suggest not using a password, but then that's just me...).
Then copy the appropriate event below (depending on your password usage), right click the sheet tab,
select "View Code" and paste the code into the window that appears.
HTH,

If you didn't use a password
Private Sub Worksheet_Change(ByVal Target As Range)
Target.Parent.Unprotect
Target.Locked = True
Target.Parent.Protect
End Sub
If you use a password:
Private Sub Worksheet_Change(ByVal Target As Range)
Target.Parent.Unprotect "PasswordYouUsed"
Target.Locked = True
Target.Parent.Protect "PasswordYouUsed"
End Sub
