Averaging out cells with formulas in them?

[Svenski79]

Hi all,

In the attached doc, I need a formula that will successfully average the cells with the orange background in the second tab. Any time I try and run an average formula over cells with formulas already in them, I get a DIV error. I've looked online and it seems quite a few other people have had the same problem. None of their suggested formulas have worked for me

Any ideas?

Doc attached!

Maybe try taking the quotes out of your formulas as they are making the numbers you are using text. ie. make "100.00" = 100

And then use this array formula to calculate the averages:

=AVERAGE(IF(MOD(COLUMN($D4:$N4)-COLUMN($D4),2)=0,$D4:$N4,0))

Array Formulae are a little different from ordinary formulae in that they MUST be confirmed in the FIRST CELL ONLY by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. After that, the array can be dragged down as normal, to cover the desired range.

You will know the array is active when you see curly brackets { } - or "curly braces" for those of you in the USA, or "flower brackets" for those of you in India - appear around the outside of your formula. If you do not use CTRL+SHIFT+ENTER you will (almost always) get an error message or an incorrect answer. Press F2 on that cell and try again.

Don't type the curly brackets yourself - it won't work...

Thankyou both! Worked like a charm.

You're welcome.
