I am trying to write a macro that resets the range used by
a Data Validation input box in a cell. I have the
validation set on a range of cells and elsewhere in the
sheet there is the list of valid input. I change the list
and need to programmatically change the validated cells,
but the following code doesn't seem to accept a named range

With Selection.Validation
.Delete
.Add Type:=xlValidateList,
AlertStyle:=xlValidAlertStop, Operator:= _
xlBetween, Formula1:="=$D$60:$D$83"
.IgnoreBlank = True
.InCellDropdown = True
.InputTitle = ""
.ErrorTitle = ""
.InputMessage = ""
.ErrorMessage = ""
.ShowInput = True
.ShowError = True
End With

I need to be able to change the abolsute range reference
following Formula1:=

Any pointers much appreciated.
