Using sumif for non contiguous ranges WITHOUT naming them

[Meredith]

For example, I want to find the sum for cells A5, A7, A9, and A11.

But A7 is a vlookup that isn't returning a value. So I want to get the sum of A5,A7,A9,A11, if they are >0

is there a way to do this without naming the range? There will be about 4000 ranges if i have to name them.

Try...

=SUMPRODUCT(--(MOD(ROW(A5:A100)-ROW(A5),2)=0),A5:A100)

Adjust the range accordingly.

Hope this helps!

not sure if i understand

I am not very familiar with the sum product and mod functions. How would they allow me to do a sum of only numerical values in a non contiguous range? is it that the remainder of the cells that have errors in them is zero?



anyway, let me give a bit more info



I have several customer pages that allow sales guys to input sales by month by product for each customer

So let's say I am trying to get the total sales by product for each month of quarter 1.

I would have each product listed on the left with their unique code. I then have, going across the columns, vlookups for the product on each customer page. Problem is, not all customers have the same products, so sometimes the vlookups come back with #VALUE unless I do an if statement with an iserror.. which takes up so much memory and slows down my computer drastically ( especially if working remotely) so I don't want to do that.


so, let's say the data is in D6, H6,L6, P6, T6 and X6. How would you put that in the formula you gave?

VLOOKUP should not be returning the #VALUE error.

Try...

=SUM(IF(MOD(COLUMN(D6:X6)-COLUMN(D6),4)=0,IF(ISNUMBER(D6:X6),D6:X6)))

...confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!

Okay, #ref not #value, sorry I misspoke.

Domenic, there are values in E6,I6,M6, etc that i do NOT want to add.

There are three months of data

I want to add all Jan,Feb, and Mar separately.



I am beginning to think I just need to adjust the way I've pulled the informatio nso all januaries are together. that way it is contiguous.

The formula won't add those values. Did you confirm the formula with CONTROL+SHIFT+ENTER, not just ENTER?

Meredith,

You may also want to re-visit the VLOOKUP formula as the #REF error is returned because the column to return is outside of your table array. The information you seek maybe in your table array.

THANKS

I hadn't realized that the 4 went ot every fourth column. That works perfectly!
