1) I am wanting to compare the current Month vs. Average (Cell AD). I thought I
could use the same formula below, and then subtract the Avg. cell from the
current month cell, but that isn't seeming to work? Any ideas?

=AVERAGE(IF($R$11:$AC$11<=S2,$R$14:$AC$14))-AD14 (Not working)

2). I would also like to have a formula to do the Delta % from Current
Month & Average that populates with each month as the average does below.
But that is not working either. The original formula I was using is
=1-(AC14/AD14) but that would mean I have to manually change this as well.
Wasn't wanting to do that...

Thanks. :)

Sounds okay. What formula did you use?

Again, show us the formula.

3) In the formula that was giving to me below, I am not understanding the
concept of these two things-can someone explain them (It does however work
wonderfully!!)?

Here is the entire formula:

=SUMPRODUCT(($R$11:$AC$11<=Q2)*$R$12:$AC$12)/SUMPRODUCT(--($R$11:$AC$11<=Q2)
)

Here are my questions:
Why multiply?
)*$R$12:$AC$12)/

Why the dashes?
--($R$11:$AC$11<=Q2))

They are used to coerce TRUE/FALSE results to 1/0 which SP can work on. I
have no idea why your responder used both, they could have stuck to one. See
http://www.xldynamic.com/source/xld.SUMPRODUCT.html for a detailed
explanation.

BTW, I would the use the simpler, and more obvious

=AVERAGE(IF($R$11:$AC$11<=Q2,$R$12:$AC$12))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.
