Sumproduct with autofilter

[John]

I am trying to use sum product I believe for the following formula.....

=(SUM(M3:M468)/SUM(F3:F468))/1440

I am trying to use auto-filter to give me the above answer for just the
fields shown after filtering. Any ideas????

Try it like this:

=SUBTOTAL(9,M3:M468)/SUBTOTAL(9,F3:F468)/1440
