Jay,

See if you can adapt this:

Sub ListCompare()
   Dim CompSheet As Worksheet
   
   Dim List1 As Range 'range of cells containing your first list eg B3:B32
   Dim List1Header As Range 'label at the top of list 1 e.g. B2
   Dim List1Item As Range
   
   Dim List2 As Range 'range of cells containing your second list e.g.D3:D32
   Dim List2Header As Range 'label at the top of list 1 e.g. D2
   Dim List2Item As Range
       
   Dim List1OnlyHeader As Range 'label above where you want items found
ONLY in first list to appear e.g.F2
   Dim List2OnlyHeader As Range 'label above where you want items found
ONLY in second list to appear e.g. H2
   Dim ListBothHeader As Range 'label above where you want items found in
BOTH lists to appear e.g. J2
   
   Dim Flag As Boolean
   
   'In my example, List1 is B3:B32 and List2 is D3:D32, although the code
works out
   'how long the lists are and allocates the names List1 and List2 to the
cells containing them (the
   'data only, not the headers).
   
   'Make sure that there is a blank column to the left of List1Header, and
blank
   'columns between List1OnlyHeader and List2OnlyHeader, and between
List2OnlyHeader and ListBothHeader.
   
   'Finally, make sure there is a blank column to the right of
ListBothHeader.
   'This ensures that all the "CurrentRegion" referenece work correctly.
   'In my example:
   '   Cell F2 contains the label "List1Only" and has a range name of
"List1OnlyHeader",
   '   Cell H2 contains the label "List2Only" and has a range name of
"List2OnlyHeader",
   '   Cell J2 contains the label "Both" and has a range name of
"ListBothHeader",
   
   'Columns A, D, E, G, I and K must be blank (or at the very least,
mustn't contain data adjacent to the
   'entries in columns B, D, F, H and K.
   'The worksheet is called "Compare Lists"
   
   Set CompSheet = Worksheets("Compare Lists")
       
   Set List1Header = CompSheet.Range("List1Header")

   Next

   'Sort List1Only list
   List1OnlyHeader.CurrentRegion.Sort Key1:=Range("List1OnlyHeader"), _
       Order1:=xlAscending, Header:=xlGuess, _
           OrderCustom:=1, MatchCase:=False, _
               Orientation:=xlTopToBottom

   'Sort List2Only list

End Sub

Hope it's of some use
