Hi Brian
you can't do this without using code ... here's some that will do what you
want, but be warned when you change the values in column D of worksheet 1
the values in the whole of column A on sheet2 are deleted and replaced with
the new values.
Private Sub Worksheet_Change(ByVal Target As Range)
Application.EnableEvents = False
Application.ScreenUpdating = False
If Target.Column = 4 Then
Sheets("Sheet2").Range("A:A").Delete
Columns("D

").Select
Selection.SpecialCells(xlCellTypeConstants, 23).Select
Selection.Copy Sheets("Sheet2").Range("A1")
Application.CutCopyMode = False
Range("D1").Select
End If
Application.EnableEvents = True
Application.ScreenUpdating = True
End Sub
This code needs to go against the Sheet1 module (right mouse click on
Sheet1's tab, choose view code - Sheet1 should be highlighted on the left
hand side of the screen - paste the code in the white sheet of paper on the
right). Oh, you will also need to ensure that your security is set to
medium (tools / macros / security)
Hope this helps
Cheers
