Adding up nth line differently

[Berandon]

I have been working on a spreadsheet for next year for a log of all my employees completed MFG/install/service time. I am trying to get it to add up all my "daily" columns and then divide by the number of days worked. My main question is how to get it to add up each one without me manually typing the cell. I can't do any kind of array because depending on how much is done each day depends on the line separation between days. anywhere from 1 line of work to 15 lines. Anyone have any ideas on what can be done, even if you don't know the coding. I may be able to figure that out. i just don't want to type 365 cells 5 times (for the amount of columns I have to add up).

Have you tried a Pivot Table? Tutorials here http://www.contextures.com/tiptech.html

I don't know enough about pivot tables to know for sure. but it still wants a range and my ranges are eg(r9,r14,r21,r23,r27,r34,,,,r2134) when i try to make a pivot table, it asks me to pick a field. I wanted to get away from having to CTRL click all 365 days 5 times

I want to see if I could attach a picture of it.

It didn't work.

It is very hard to explain what i need to do. i have columns D M O P that i need to add up and average but i cant use an array that just does every 2nd 3rd 5th etc because they are ever changing. Right now i have them add up and then average of screen, but i need to do it for every day of next year and it is alot of work manually typing $D$9 all the way down the list. for 4 (maybe 5) times.
