Hi,
I have came up with my own solution for this but I am not if its the neatest approach to do it.

all I am trying to do is to get the monthly average of the price for the dates and populate against the cells. (in VBA)
Please see the attahed file.
It would be great if some one provide me with code that would populate the 'Monthly Avg' - Column C with the price average for that month.

Many thanks

Hello,

any particular reason for VBA? A formula would be much faster. Start in C2

=AVERAGE(IF(MONTH($A$2:$A$24)=MONTH(A2),$B$2:$B$24,""))

Confirm with Ctrl-Shift-Enter and copy down.

cheers, teylyn

Here's one possibility to do it in code

Sub Macro2()
Dim lRow As Long
lRow = Cells(Rows.Count, "A").End(xlUp).Row
    Range("C2").FormulaArray = _
        "=AVERAGE(IF(MONTH($A$2:$A$" & lRow & ")=MONTH(A2),$B$2:$B$" & lRow & ",""""))"
    Range("C2").AutoFill Destination:=Range("C2:C" & lRow)
    With Range("C2:C" & lRow)
        .Copy
        .PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
            :=False, Transpose:=False
    End With
    Application.CutCopyMode = False
    Range("C2").Select
End Sub

Thanks but in this case the records would go beyond one year
That is multiple years.
so we would have to add check for multiple years too.
I tried,

=AVERAGE(IF(AND(YEAR($A$2:$A$24)=YEAR(A2), MONTH($A$2:$A$24)=MONTH(A2)),$B$2:$B$24,""))

But it fails. Because its trying to locate the same value in the whole range.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

AND() does not work in this context. You can use this instead:

=AVERAGE(IF((YEAR($A$2:$A$24)=YEAR(A2))*(MONTH($A$2:$A$24)=MONTH(A2)),$B$2:$B$24,""))

Remember to confirm with Ctrl-Shift-Enter

Thanks. That seems to work fine
Although I have written a module too (which works :)) using loops but I think your would be much quicker.

I have another very quick one.
I am trying to freeze pans.
Go select row -> window -> freeze pane -
for some reason it is freezing on 16 rows

tried doing it from VBA too. Get the same result
'ActiveWindow.FreezePanes = True'

How can I do it from VBA such that it would freeze on header/first row?

Thanks
