SUMPRODUCT not working properly

In my workbook there is a small example table of what I am trying to use.

The test data runs from B2 through to AE23

Column B and Column C have resource numbers in them.

Column D-AE have hours per day.

The SUMPRODUCT should take the value from column B, divide it by the sum of column B,C to get a percentage, then multiply it by the hours per day from column D through AE to get a daily total.

The second SUMPRODUCT should do the same, but use column C divided by the sum of B,C to get a percentage then multiply it by the hours per day from column D through AE to get a daily total.

Help.....

It sounds what you want is:

=SUMPRODUCT($B2:$B23,D2:D23)/SUM($B2:$C23)

and

=SUMPRODUCT($C2:$C23,D2:D23)/SUM($B2:$C23)

This latter in column D with give 4 * 10 / 63.

Without knowing whether that is truly what you want, I cannot go any further. Is that the right answer?

Sorry, not even close.

For Column D values and "MW" it should use:
B2/(SUM(B2,C2)*D2 = 0
B3/(SUM(B3,C3)*D3 = 0
B4/(SUM(B4,C4)*D4 = 0
B5/(SUM(B5,C5)*D5 = 0
B6/(SUM(B6,C6)*D6 = 0
B7/(SUM(B7,C7)*D7 = 0

all the ways down....

For Column D values and "WD" it should use:
C2/(SUM(B2,C2)*D2 = 0
C3/(SUM(B3,C3)*D3 = 0
C4/(SUM(B4,C4)*D4 = 0
C5/(SUM(B5,C5)*D5 = 0
C6/(SUM(B6,C6)*D6 = 0
C7/(SUM(B7,C7)*D7 = 40

All the way down....

Column E values and "MW" it should use:

B2/(SUM(B2,C2)*E2 = 0
B3/(SUM(B3,C3)*E3 = 0
B4/(SUM(B4,C4)*E4 = 0
B5/(SUM(B5,C5)*E5 = 0
B6/(SUM(B6,C6)*E6 = 0
B7/(SUM(B7,C7)*E7 = 0

All the ways down.....

Column E values and "WD" it should use:

C2/(SUM(B2,C2)*E2 = 20
C3/(SUM(B3,C3)*E3 = 0
C4/(SUM(B4,C4)*E4 = 0
C5/(SUM(B5,C5)*E5 = 0
C6/(SUM(B6,C6)*E6 = 0
C7/(SUM(B7,C7)*E7 = 40

All the way down.....

let's concentrate on

C7/(SUM(B7,C7)*D7 = 40

B7=0, C7=4 and D7=10

So, according to your formula, you have

4/(4+0)*10. This equals 10, not 40.

Would you please clarify what you want.

Sorry, you are right Phillip.... It has been a very long day.... 10 is correct.

As I understand it, you want to calculate the percentage for each row, then multiply that with the value in column D, and finally add the values.
Try this array formula for MW (D25)
=SUM((IFERROR($B$2:$B$23/($B$2:$B$23+$C$2:$C$23)*D2:D23,0)))

And the similar for WD (D26)
=SUM((IFERROR($C$2:$C$23/($B$2:$B$23+$C$2:$C$23)*D2:D23,0)))

The formulas must be entered with Ctrl+Shift+Enter

You can use:
 
=SUMPRODUCT($B2:$B23,D2:D23,1/($B2:$B23+$C2:$C23+0.000000000001))
 
and
 
=SUMPRODUCT($C2:$C23,D2:D23,1/($B2:$B23+$C2:$C23+0.000000000001))
