Solved: Rolling average

[Northender]

I was hoping somebody would be able to help me get started on converting some excel formula into VBA. I have a spreadsheet that is updated from various other workbooks with usage data on a daily basis. This is done via a vba button. What I would like is for this button to also update the moving average for each line. I have wrote the formula for this, but would really like to consolidate into one cell that is updated for each line. Problem is I dont know where to start to convert this.

Please see attached sample sheet

Thanks

This is worksheet event code, which means that it needs to be
placed in the appropriate worksheet code module, not a standard
code module. To do this, right-click on the sheet tab, select
the View Code option from the menu, and paste the code in.

xld,

Thankyou for your reply. Unfortunately I may not have made myself clear enough in my original post, for this I apologize. I have tried to work through your code to extract what I need to make it work but dont seem to be able to do this correctly. To clarify what it is I am trying to do.

In my sheet that I attached I have information that runs in rows 2 to 10 and along columns D to AI. This is updated by pressing a button and being extracted from various workbooks. What I then want to happen is for AJ to be updated with the average from the last five days figures ( >0 ). I know the formulas to do this, as layed out in the lower section. I dont want to place all these columns at the end to do the calculations, rather a code to carry out the calculation and then drop the answer in. Ideally I want to place this code at the end of the extraction process.

I apologize if I have wasted your time with this, although I have learned a bit from reading the code, just seems not quite enough to solve the problem.

Public Sub ProcessData()
Dim mpLastRow As Long
Dim mpDataCol As Long
Dim mpSum As Double
Dim mpCount As Long
Dim i As Long, j As Long


With ActiveSheet

mpLastRow = .Cells(.Rows.Count, "A").End(xlUp).Row

For i = 2 To mpLastRow

If .Cells(i, "D").Value <> "" Then
mpDataCol = .Range("A" & i).End(xlToRight).Column
.Cells(i, "AJ").Value = mpDataCol - 3
If mpDataCol - 4 < 4 Then mpDataCol = 8
mpSum = 0: mpCount = 0
For j = 1 To 5
.Cells(i, 36 + j).Value = .Cells(i, mpDataCol - j + 1).Value
mpSum = mpSum + .Cells(i, mpDataCol - j + 1).Value
If .Cells(i, mpDataCol - j + 1).Value > 0 Then mpCount = mpCount + 1
Next j
.Cells(i, "AP").Value = Round(mpSum / mpCount, 0)
End If
Next i
.Range("AJ2:AO" & mpLastRow).BorderAround Weight:=xlThin
.Range("AJ2:AJ" & mpLastRow).BorderAround Weight:=xlThin

End With

Thanks for your help with this, hopefully just one more question...

[vba] Next j
.Cells(i, "AP").Value = Round(mpSum / mpCount, 0)
End If [/vba]

Can you just help with if this is an error. I have just come across a line with all zero's in, which causes an overflow error in the script.

[Bob Phillips]

Replace that line with

[vba]

If mpCount = 0 Then
.Cells(i, "AP").Value = 0
Else
.Cells(i, "AP").Value = Round(mpSum / mpCount, 0)
End If
[/vba]
