Yes it really works. I used "Subtotal" twice to cover two columns with auto
filters.
Thanks!

Hi,
How can I use sumproduct function and igore hidden value. The function usage
likes below:
=sumproduct((range1=criteria1)*(rang2=criterial2)* rang4), and I am using
filter on range3.
I expect the function result can igore the any hidden value I made on range 3.

P.S. each range is one column with same row number.

Thanks,
