I have a workbook with 31 worksheets.
One worksheet for everyday of the month.
They are named 1,2,3,...29,30,31
I am having trouble writing a macro to do the following.
In Range("k16") is a value on each worksheet.
On the worksheet #2 i want to average the value of k16 of the first and second sheet.
On the worksheet #3 i want to average the value of k16 of the first, second, third worksheet. I hope you follow my logic.
Of course I don't want to average all worksheets until that day has come to the corresponding worksheet.
I want to put the average for day 1 & 2 on the second worksheet in let's say Range("k17").
Getting caught up in opening sheets or correct order.
Thankyou, Bob

Code:
Sub daysAvg()
Dim currDay As Integer
currDay = Day(Date)
For i = 2 To currDay
    Sheets("" & i).Select
    Sheets("" & i).Range("K17") = (Sheets("" & (i - 1)).Range("K16") * (i - 1) + Sheets("" & i).Range("K16")) / i
Next i
End Sub
Try This

This is also possible using only formulas, although it's ugly.

Basically, you can use the fact that this formula gives you the name of the current worksheet as a number:

=MID(CELL("filename",A1),FIND("]",CELL("filename",A1))+1,31)*1

And this one tells you what's in the previous sheet's cell K17:

=INDIRECT(((MID(CELL("filename",A1),FIND("]",CELL("filename",A1))+1,31)*1)-1)&"!K17")

Oh, and this gives you the number of the current day:

=DAY(TODAY())

Combine things in the same way nightcrawler did in his code and voila! Easy as pie. :)
