Sheet1​

Hello forum
I wish to modify the formula, (below), to give the results between S1 and AI1.
[TABLE="width: 403"]
<colgroup><col></colgroup><tbody>[TR]
[TD]'=SUM(INDIRECT("A1:"&SUBSTITUTE(ADDRESS(1,COLUMN(),4),1,"")&"1"))'
Thank you
David Wale
[/TD]
[/TR]
</tbody>[/TABLE]
_{^{<strike>

How about in S1 dragged right
=LOOKUP(2,1/($A$1:A1<>""),$A$1:A1)

 

[Aladin Akyurek]

In S1 enter and copy across:

=LOOKUP(9.99999999999999E+307,$A$1:A1)

which is faster.

Thank you Fluff, for your 'lookup' formula, it is exactly what I require.
Yours cordially

You're welcome & thanks for the feedback.
You should also look at Aladin's simpler & faster solution.
