Hi John
only possible with VBA. You may try the following macro (put this in
your workbook module - not in a standard module):
Private Sub Workbook_BeforePrint(Cancel As Boolean)
Dim wkSht As Worksheet
For Each wkSht In Me.Worksheets
With wkSht.PageSetup
.LeftFooter = wkSht.range("A1").value
.RightFooter = wkSht.range("B1").value
End With
Next wkSht
End Sub
