I am trying to find a group of functions that allows me to calculate the avarge of a dynamic range for a pivot table. I know I have to use Offset & Counta however even when I change the data it only picks up the amount that I initially inputed.
For Example:
I have two sets of pivot table data. One with only 4 weeks and the grand total and the other with 5 weeks and the grand total. I used the function for data 1 (4 weeks) = Average(Offset, C3, 0, 0, (Counta (C3)), Counta (C3:F3))).
On the left (A3:A5) I am given the average. If I were to add a week 5 as seen in the second data It still only picks up C10:F10 and not E10 (week 5).
I am trying to find a function that allows me to pick up the average of the weeks ** without ** the grandtotal in it. So if I were to add 10 weeks the average were to automaticlly pick up the range C10:C20. and not the grandtotal.
