Hi,

You could try something like this as well:

=(sumif(M6:M199,"=-9.99999E307")/sumif(P6:P199,"=-9.99999E307"))/1440

How do I get a subtotal when the data I am Subtotaling contains #n/a
without
returning an answer of #n/a.


I am using =SUBTOTAL(9,M6:M199)/SUBTOTAL(9,P6:P199)/1440

This formula takes total time in seconds divided by total calls divided by
1440 and the cell is formated to time. The answer should return a time in
minutes and seconds; however, it returns #n/a. How would I get the formula
to
ignore the #n/a in the data set that it is calculating?
