Hi, I am trying to make a field in a sheet mandatory so that when the

prompted that they must fill in a particular cell.

I have used the following code before to make a field compulsary before
the user closes the whole file but I don't know how to adapt it to work
when they leave the sheet:

Private Sub Workbook_BeforeClose(Cancel As Boolean)
Dim checkRng As Range
Set checkRng = Sheets("Sheet1").Range("A1")
If checkRng.Value = "" Then
Cancel = True
MsgBox "Please fill in " & _
checkRng.Address(False, False) & "."
End If
End Sub


Any help would be very much appreciated, thanks

Put the following in the worksheet code area (NOT workbook code area) of the worksheet in question:

Private Sub Worksheet_Deactivate()
Dim checkRng As Range
Set checkRng = Sheets("Sheet1").Range("A1")
If checkRng.Value = "" Then
Sheets("Sheet1").Activate
MsgBox "Please fill in " & _
checkRng.Address(False, False) & "."
End If
End Sub
