Hello all!
I wish to obtain the average of a number of numeric cells but wish this
average to be ongoing rather than restricted to a range of cells.

For example
=AVERAGE(D13:D17) will only give the average of the cells D13 to D17 but I
will be continually adding more data and wish for this to be calculated in
the average also.

My overall objective here is to carry out evaluations on staff performance
and as each new review arrives from a client regarding a staff member, I will
be adding a new row to include this data.Therefore need to have the number of
all reviews received whether it be five or fifty to be calculated in the
overall average.

I have not been able to identify anything in the application help to cover
this use of the average function and help will be greatfully appreciated

Cheers Sherry
