The Sub below is intended to extend the "Range1" to cover any new items in
column A and to enter conditional formatting to highlight any duplicates.

It works fine UNLESS the instruction "thisrange.Select" is removed. When
this is removed cell A1 ends up with the conditional format formula
"=(COUNTIF(Range1,A65527)1)"

Public Sub rangered()
Set orig = Selection
Set thisrange = Range("a1",
Worksheets("Sheet1").Range("A1").End(xlDown))

thisrange.Select

thisrange.FormatConditions.Delete
thisrange.FormatConditions.Add Type:=xlExpression,
Formula1:="=(COUNTIF(Range1,A1)1)"
thisrange.FormatConditions(1).Interior.ColorIndex = 3
ActiveWorkbook.Names.Add Name:="Range1", RefersTo:=thisrange
orig.Select
End Sub

relative references in a conditional format are relative to the activecell.
So you need to select Range("A1") before applying the conditional format.
