Hello!

I'm trying to come up with a way to sum a certain number of columns within a range. I have 12 columns (Jan-Dec) with data in them, but I want to sum only from like Jan-Jun without having to update all the formulas all the time, I think I should be able to have a formula with the entire range of columns but only returning the the number of columns I need every month. I think by adding this number in a separate cell like 6 for June or something like that.

How would I go about creating this formula?

Thanks in advance!

Yes! Use "0101011" for the weekend argument in NETWORKDAYS.INTL or WORKDAY.INTL. The 7 digits start on Monday. 1 means it is a weekend.

This works, I just changed the second Index range to be within the same row since I need a total for each row (each account).

Thanks a lot for your help!

This is awesome.

If it's within the same row, there's a shorter formula you can use involving OFFSET. But I'd recommend sticking with the current formula because it's pretty easy to see how to adapt it for other cases, as you've seen! :LOL:

Glad we could help!
