Hi Bernie,
The "Dim ForceChange As Boolean
Dim myRow As Long" part is outside the sub and gives an error message.
I already have a 'worksheet change' event on the sheet so I added your code
to it, but it didn't do anything.
The sheet is password protected - could that be the problem?

Thanks,

WorksheetFunction.CountBlank(myR.Areas(2)) 0 Then
myRow = Target.Row
ForceChange = True
Else
ForceChange = False
End If
End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
If Not ForceChange Or Target.Row = myRow Then Exit Sub
Application.EnableEvents = False
Intersect(Range("D:E,H:H"), Cells(myRow, 1).EntireRow) _
.SpecialCells(xlCellTypeBlanks)(1).Select
MsgBox "Please enter a value in cell " & Selection.Address
Application.EnableEvents = True
End Sub

I need to ensure that certain cells in every row are filled in by the user.
How can I add code to force data input into, say, columns D, E and H when
the user navigates to the next row? Perhaps a popup box informing the user
and highlight the empty cell(s) in yellow for instance? Can the user then not
be able to continue until the empty cell(s) are filled in?

Thanks,
