Dear Experts:

I would like to run a macro that ...
... counts the number of unique and duplicate values in two named ranges on the current worksheet and
... displays these values in a msgbox

Please find the detailed explanation as well as the sample file below.

Help is much appreciated. Thank you very much in advance.

Regards, Andreas

Do you need it in a macro. It is possible to do this by formula.

Hi Philipp,

thank you very much for your quick feedback. As a matter of fact, I would like to use this macro along with other macros so actually the macro way would be my favourite approach. But to be honest with you, the formula solution would be very nice to know, keeping in mind that the ranges on the active worksheet can vary, i.e. the number of rows.

Regards, Andreas

To find the distinct values in the first range, enter

=SUM(1/COUNTIF(B2:B9,B2:B9))

but don't press Enter. Instead, press Alt+Shift+Enter.

You should then see the answer "3".

This macro ought to do the trick:

Sub CountThem()
    
    Dim rng1 As Range
    Dim rng2 As Range
    Dim Counter As Long
    Dim coll1 As Collection
    Dim coll2 As Collection
    
    On Error Resume Next
    
    Set rng1 = ThisWorkbook.Names("Range_1").RefersToRange
    Set coll1 = New Collection
    For Counter = 1 To rng1.Rows.Count
        coll1.Add rng1.Cells(Counter, 2).Value, rng1.Cells(Counter, 2).Value
    Next
    
    Set rng2 = ThisWorkbook.Names("Range_2").RefersToRange
    Set coll2 = New Collection
    For Counter = 1 To rng1.Rows.Count
        coll2.Add rng2.Cells(Counter, 2).Value, rng2.Cells(Counter, 2).Value
    Next
    
    MsgBox "Range_1 has " & coll1.Count & " distinct items and " & rng1.Rows.Count - coll1.Count & " duplicates" & _
        vbCrLf & vbCrLf & _
        "Range_2 has " & coll2.Count & " distinct items and " & rng2.Rows.Count - coll2.Count & " duplicates"
    
    Set coll1 = Nothing
    Set coll2 = Nothing
    
End Sub

A2 = A1 That kind of cell reference is relative.  If you copy it from A2 to B2, then B2 will get this: B2 = B1 That's all fine and good, but if you then insert a new row above row 2, you'll find: A3 = A1 B3 = B1 This is intentional. …
