Hi

I have a row in which i input values on a daily basis, and i need these values to be added, until i insert a 'x' in a cell which will reset the sum total, thereafter the cumulative sum will only be after the last cell containing an 'x'.

Assuming i have 365 Columns representing each day in the year, what formula (or macro) can i use in cell 366 that can add values (including blank cells) in a row, but only sum the values after the last cell containing an "x"


Is this possible?
Thanks

Hi

Yes, this formula is exactly what I want, and it works 100% as intended, thank you very much for your assistance.

Slightly different computation, using the post #2 representation...

Control+shift+enter, not just enter, and copy down

=IFERROR(SUM(INDEX(A2:K2,MATCH(9.99999999999999E+307,1/(A2:K2="x"))):K2),0)
