Hi, i am using Excel 2010. I have a column of values in column H, and i need to check when the values in column H sum to 1 or just over, and then sum values in another column which correspond to the rows which sum to one or just over (sorry I know I am not explaining this too well- it's difficult to word). So, for example, if the below was in columns H and I:

H. I

row2. 0.331. 100

row3. 0.804. 200

row4. 0.511. 150

row5. 0.530. 230

row6. 0.493. 120

row7. 0.337. 80

row8. 0.452. 90

row9. 0.919. 150

and so on, in column J row2 I would want it to sum H row 2 and 3, which is greater than one, so it would then sum I 2 and 3, and then in column J row3, it would sum row 3 and 4, which is greater than 1 so then would sum the values in column I, rows 3 and 4. But then in row 7, it would have to sum the values in rows 7 to 9 to reach a value greater than one, and so would then sum the values in column I for rows 7 to 9.

I tried a version of a sumproduct array formula but I can't get it to work properly. Your assistance with a formula that could do this would be much appreciated. Please let me know if I should rather email you my sheet as it may make more sense.

Kind regards,

Sarah

Sarah,

sure, emailing your sheet would probably be much better. So basically, summing column H determines where the sum of values from column I will appear. In you example, you sum row 3 in two places which I believe is an error in your explanation. I would see sums in

J3 =sum(I2:I3)

J5 =Sum(I4:I5)

J8 =Sum(I6:I8)

I assume J4, J6, J7, would appear blank

So if I am wrong, then clarify the rules when you send the file
