I have figures in col E of a ss, separated into races.  I want to return a value for each race that is the maximum of the values in col E pertaining to that race.  I have tried to code it by allocating variables to the top and bottom cell of each appropriate range, but I can't make that work.  Please could someone show me the proper way to do it, thanks.

where do you want the value to be?  have you considered the 'Max' formula?

This perhaps?
Sub x()

Dim r As Range

For Each r In Columns(3).SpecialCells(xlCellTypeConstants).Areas
    r(1).Offset(2, -2) = WorksheetFunction.Max(r.Columns(3))
Next r

End Sub

Open in new window

Try a macro like this:
 
Sub GetMaxValues()
    r = 2
    e = 0
    Dim rng As Range
    Do While e < 4
        If Cells(r, 3).Value = "" Then
            e = e + 1
            If e = 1 Then
                Cells(r, 5).Formula = "=Max(" & rng.Offset(0, 2).Address & ")"
                Set rng = Nothing
            End If
        Else
            e = 0
            If Not rng Is Nothing Then
                Set rng = Union(Cells(r, 3), rng)
            Else
                Set rng = Cells(r, 3)
            End If
        End If
        r = r + 1
    Loop
End Sub

Open in new window


It will go down the list, and insert the MAX function in the first empty cell after each list, for that list.

This code assumes that if we find 4 consecutive blank rows, the end of the data has been reached, and that there are no blank rows within each list.

Good luck!

select cell A4
enter the following contents :

=max(E3:E29)

the 'equals' sign indicates that cell A4 contains a formula and not a text or a value
the 'max' formula represents the utmost positive value of the supplied cells
the supplied cells range from E3 up to E29 (being values corresponding to a single race)

KnutsonBM Thanks.  Yes, I considered the Max formula, couldn't make it work with VBA though.
StephenJR, McOz - great solutions, thank you very much - and for explanatory comments which are always helpful, cheers.  Now I'm going to see if I can work out how it has been done.  EE is my saviour and my tutor!
akoster, thanks for your explanations - I was looking for VBA.
