Hi,
I'm tyring to find a way to sum a series of cells in a single row until a cell is reached who's value = 0.

Example:

Row1 cells (columns A thru D then E contains "0")

A=1; B=3; C=7; D=9. Then a "0" is detected in cell Column E of row1 so only values A,B,C,D are summed equaling 20.



There are multiple rows (35 altogether) and the "0" can show up in any column A thru U or not at all.

thank you.

Hi Perhaps something like

Thanks! I'll give it a whirl.

Hi Pecoflyer,
I modified what you gave me slightly and it worked perfectly except I need this formula to work "left to right"...going from Column "U" towards Column "A" so it SUMS cells going from U2 towards A2 (in this example) until a cell containing value "0" is found.
Can you adjust the formula below to do this? Thank you again.
=SUM(OFFSET(A2,,,,MATCH(0,A2:U2,0)))

Pecoflyer,
I meant right to left in my last comment...sorry about that!

Perhaps

Hi Pecoflyer,
This was very close:
=SUM(a2:u2)-SUM(OFFSET(A2,,,,MATCH(0,A2:U2,0))).

But it adds cells together to the first cell="0" from Right-to-Left + Left-to-Right.
I was looking for only the Right-to-Left if you can modify.

thank you again for your diligence.

sunny

Sorry, I wrongly assumed there would only be one 0 in the row
Is this better ?

Hi Pecoflyer,

Here's the string to assist. Sorry I didn't provide this detail earlier:

Assume a single row with columns A1 thru U1.

10, 12, 1, 2, 0, 3, 6, 7, 18, 20, 0, 3, 4, 30, 10, 12, 11, 0, 2, 1, 7

A1 = 10 and U1 = 7.

The formular should work Left-to-Right starting with U1 and, in this case the answer would be 7+1+2 = 10.

Regards.

Right to Left....I'm dyslexic

I hope I did it right this time - See attached - Also see comments
