If I want to work out the average sum of say, for example, 5 cells in a
row, I would simply write =SUM(A1:A5)/5 in this case. If however, I wanted
the computer to work out the average of the sum in a number of cells, only
if there was data in the cells, how would I write this? Say for example, I
have 5 cells in a row, with no data in one of the cells. That would effect
the average, so how do I write a formula whereby, if there is no data in the
cell, then the formula will ignore that cell???
Thanks
