Being an AVID proponent of using the asterisk form of SumProduct, mainly
because the "regular" asterisk syntax in these groups always exposes
(coerces) the numerical range to a mathematical operator, I would *never*
have attempted a unary solution to this post.

In fact, I answered a similar post a couple of days ago with almost the
exact same type solution:

http://tinyurl.com/gt8f3

Where the ranges varied.

The only reason I gave this thread a second thought was because Bob was the
author of the suggestion, and Bob doesn't use the asterisk form.
I just wondered why he did use it here, and I soon found out when I tried
the unary in his formula.

Thanks for the explanation.

Just another reason why I feel the asterisk form should be the primary
syntax of choice.<bg

Might you explain Bob?
[...]

SumProduct with the comma-syntax requires equally sized objects. Put
otherwise:

SumProduct(Vector1,Vector2,...)
SumProduct(Matrix1,Matrix2,...)

but not:

SumProduct(Vector1,Vector2,...,Matrix1,...)

If you switch to using the multiplication operator ("the star syntax"), it
behaves like MMult.

BTW, the OP's question doesn't require SumProduct at all.

=SUMPRODUCT((Sheet1!B1:M1=A1)*(Sheet1!A3:A20=Sheet 2!B1)*(Sheet1!B3:M20))

adjust the ranges to suit

Hey everyone, I am not sure what the best way is to handle this so
I
thought
that maybe some of you could help point me in the right
direction. In
my
worksheet (Sheet1) I have the following data:

Sheet1:

a b c d
e
f
1 Promo1 Promo1 Promo2 Promo2
Promo2
2 Week1 Week2 Week3 Week4
Week5
3 Menu Item1 .2 .3 .15 .26
.16
4 Menu Item2 .4 .28 .56 .6
.68
5 Menu Item3 .25 .32 .45 .8
.15

And just to specifiy there are many more promo's and many more menu
items
in
my sheet so this is an oversimplification of the data.

That being said, I would like to sum the data for a specific
Menu Item
based
on which promo it falls under. For example:

Sheet2:

a b c
1 Promo2 Menu Item2 1.84


Any help on the best way to do this would be greatly appreciated.

Thanks in advance for all of your help.

Beset,
Chad
