A tad more detail might be useful.

Bob,
What you have stated here doesn't work for me.

1) I am now wanting to compare the current Month vs. Average. 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?

Sounds okay. What formula did you use?

2). I would also like to have a formula to do the Delta % from
Current
Month & Average that changes with each month as the average does
below.
But
that is not working either.

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.
