I have a formula on a range of cells in column K, I want excel to sum the
values of of all the cells in that range; that ARE numbers. (Somo of the
cells show "#N/A", because the formula does not return number values in all
I believe I have to combine the SUMIF and ISNUMBER functions; but I don't
know how to do it.
If there are negative numbers in your list, then use a negative number much
larger than you will ever have. eg
