User

I want the number on L1 to be automatically added to the numbers I put into c thru k so the total is shown on L2 automatically as I input numbers on lines c3,4,5,6,etc.

Excelchat Expert

L1 is the sum of cells C2 to K2?

Excelchat Expert

no c1 has the number 2, d has no number, e has number 3, e has no number, f has number 5 then l would have an answer of 10

Excelchat Expert

User

c2 has a number of 6 -What would L have and what is the formula to get the new sum automatically into L when I input the number to c2.I want to continue this process for all successive lines.

Excelchat Expert

"What would L have " you mean L1?

User
03/05/2018 - 01:11

yes Li then L2 and so on to L10000

Excelchat Expert
03/05/2018 - 01:12

on C2 you type 6, and the answer of L2 is the sum of C2 to K2 plus L1?

User
03/05/2018 - 01:13

yes and continue that same process for as many lines as I need

Excelchat Expert
03/05/2018 - 01:14

Excelchat Expert

I used a IF function to check if column C of that line has value. If it has value, then L is sumed, otherwise, L3 is blank

Excelchat Expert

Is this formula OK? Or it was not what you need?

User
03/05/2018 - 01:17

yes that is what I want to do Please give me the formula so I can copy it down

Excelchat Expert
03/05/2018 - 01:17

=if(C2<>"",SUM(C2:K2)+L1,"")

Excelchat Expert
03/05/2018 - 01:17

you copy this formula on cell L2

Excelchat Expert
03/05/2018 - 01:18

and then you can paste to the lines above L2
