I need to count number of columns in group -
I have a matrix with SUM in the date area.
I have a group column (lats say 'city') and under it my columns (lats say 'street name');
Under each 'street name' I have cell with SUM function.
The problem is:
When The main group (city) is not expand I get the sum of all cities and what I want to get is an average.
So what I thought of was to divide that number in the number of streets under each city group.
How can I get that number?
