Small & multiply if function combo

[cgsierra]

I am trying to make a formula which gives me the smallest operating PROFIT of a subtotaled data set that only contains Revenue (column B) and Margin (column C). In other words:
A1=x, B1=$10, C1=5%
A2=x, B2=$20, C2=3%
A3="subtotal x", B3=$30, C3=3.7%
A4=y, B4=$40, C4=8%
A5=y, B5=$20, C5=7%
A6=y, B6=$50, C6=15%
A7="subtotal y", B7=$110, C7=11%
A8=z, B8=$100, C8=7%
A9=z, B9=$20, C9=10%
A10="subtotal z", B10=$120, C10=7.5%
The formula should return: $1.11 (which is 30*3.7% which is the smallest of the 3 operating profits of the subtotals)
I am using: {=SMALL((MMULT(GAM!$S$9:$S$34,GAM!$T$9:$T$34))*(GAM!$C$9:$C$34="Sub-Total"),1)} but I keep getting a #value! message.
Your help is greatly appreciated!

not too sure on the MMULT function so I looked it up

The number of columns in array1 must be the same as the number of rows in array2, and both arrays must contain only numbers.
Array1 and array2 can be given as cell ranges, array constants, or references.
MMULT returns the #VALUE! error when:

• Any cells are empty or contain text.
• The number of columns in array1 is different from the number of rows in array2.

Looking at this you have a lot wrong with your formula.
you have all columns and you appear to be looking up text


I think you need another fourmula altogether

Thank you. In terms of array 1 (column B) and array (column C), they are both only numbers and contain the same array size. However, there are blank spaces, which I need for presentation purposes. I would enter dummy figures and color white in the empty spaces but the data set changes and it is a big database. Can you recommend another formula?

Untested, but this CSE formula might do it

=SMALL(IF(A1:A10="subtotal", B1:B10*C1:C10, 9E+99), 1)

This formula should be entered with Ctrl-Shift-Enter (Cmd+Return for Mac)

The applicable formula with the data set above is actually:
{=SMALL((MMULT(GAM!$B$1:$B$10,GAM!$C$1:$C$10))*(GAM!$A$1:$C$10="subtotal"),1)}, instead of the original I posted, sorry if this caused any confussion.

This is EXACTLY what I was looking for! Thank you!!
