## Sum unique numbers

The formula in cell D3 adds all unique numbers in cell range B3:B12 and returns the total. Unique values are all values occurring only once in the list.

Formula in cell D3:

### Explaining formula in cell D3

#### Step 1 - Count occurrence of each value in cell range

The COUNTIF function is an extremely useful function, this time I am counting how many times each value shows up in the cell range.

COUNTIF(B3:B12,B3:B12)

becomes

COUNTIF({40; 10; 80; 40; 60; 90; 40; 20; 20; 60},{40; 10; 80; 40; 60; 90; 40; 20; 20; 60})

and returns

{3;1;1;3;2;1;3;2;2;2}

#### Step 2 - Check if value is unique

The equal sign checks if number is equal to 1.

COUNTIF(B3:B12,B3:B12)=1

becomes

{3;1;1;3;2;1;3;2;2;2}=1

and returns

{FALSE; TRUE; TRUE; FALSE; FALSE; TRUE; FALSE; FALSE; FALSE; FALSE}

#### Step 3 - Multiply with cell range

The boolean values in the array show which numbers to include in sum. FALSE is the same as 0 (zero) and TRUE is equivalebt to 1. The parentheses make sure that the comparison is calculated before multiplying.

(COUNTIF(B3:B12,B3:B12)=1)*B3:B12

becomes

{FALSE; TRUE; TRUE; FALSE; FALSE; TRUE; FALSE; FALSE; FALSE; FALSE}*B3:B12

becomes

{FALSE; TRUE; TRUE; FALSE; FALSE; TRUE; FALSE; FALSE; FALSE; FALSE}*{3;1;1;3;2;1;3;2;2;2}

and returns

{0;10;80;0;0;90;0;0;0;0}

#### Step 4 - Sum numbers

The SUMPRODUCT function now simply adds the numbers and returns the total.

SUMPRODUCT((COUNTIF(B3:B12,B3:B12)=1)*B3:B12)

becomes

SUMPRODUCT({0;10;80;0;0;90;0;0;0;0})

and returns 180 in cell D3.

Why use the SUMPRODUCT function and not the SUM function? You don't need to enter this formula as an array formula if you use the SUMPRODUCT function.

I have given up trying to figure out the following problem as it seems over my head, and am

hoping there is a kind soul out there can help me out with the solution.

I am trying to setup a spreadsheet to make calculations which are then exported to Quickbooks.

The original data is returned to Excel from an Access database by msq. Each record relates to an order number and is tied to a

product, and there may be more than entry for each order number as an order may have more than one product.

The actual data import sheet looks something like this:

OrderNumber ItemNumber Date Product PricePerUnit CostPerUnit

4967 1 10-May-10 widget 430.92 306.00

4967 2 10-May-10 doohickey 256.33 165.00

4968 1 11-May-10 doohickey 256.33 165.00

The actual data export sheet looks something like this:

Date Name Account Account Type MEMO Split Account Amount

10-May-10 vendor1 Bank Credit Card 4967 Cost of Goods Sold -306.00

10-May-10 vendor1 Bank Credit Card 4967 Cost of Goods Sold -165.00

11-May-10 vendor2 Bank Credit Card 4968 Cost of Goods Sold -165.00

My problem is that I cannot figure out how to return the total only, and not individual amounts, for orders

with more than 1 item. I.E., how can I tell excel to return each OrderNumber only once, along with

the total for each, like this:

Date Name Account Account Type MEMO Split Account Amount

10-May-10 vendor1 Bank Credit Card 4967 Cost of Goods Sold -471.00

11-May-10 vendor2 Bank Credit Card 4968 Cost of Goods Sold -165.00

There is a little more to this, as I am also trying to include shipping costs, but I Am still trying to

figure out how to return the data using msq, which I am finding a little quirky to use at all, but I have

managed to at least get it to work on a basic level.

Anyhow, is there anyone there who can help? I would be very grateful and much obliged.

Thanks in advance.
