Sum previous cells if previous cell was zero

[KayserDK]

Hello,

I'm stuck and I hope you guys can help me with this simple problem.

I'm trying to get the market returns (A) to sum over the days where the stock returns (B) is not available. I have tried with if and lookup function but I can't get it right.

I have copied a small section of the issue.

Best regards

If Column A all data are numeric value and % are in cell format

Then, in C2 formula copied down :

=IF((B2<>"")*(B1=""),SUM(INDEX(A$1:A1,MATCH(9^9,B$1:B1)+1):A2),IF(B2<>"",A2,""))

Try this array formula

<table border="1" cellspacing="0" style="font-family:Calibri,Arial; font-size:11pt; background-color:#ffffff; "> <colgroup><col style="font-weight:bold; width:30px; " /><col style="width:93.15px;" /><col style="width:82.69px;" /><col style="width:100.75px;" /></colgroup><tr style="background-color:#cacaca; text-align:center; font-weight:bold; font-size:8pt; "><td > </td><td >A</td><td >B</td><td >C</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >1</td><td >Market</td><td >Stock</td><td >Result</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >2</td><td style="text-align:right; ">-0.82%</td><td style="text-align:right; ">-1,49%</td><td style="text-align:right; ">-0.82%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >3</td><td style="text-align:right; ">1.22%</td><td style="text-align:right; ">-0,77%</td><td style="text-align:right; ">1.22%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >4</td><td style="text-align:right; ">1.25%</td><td style="text-align:right; ">-0,27%</td><td style="text-align:right; ">1.25%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >5</td><td style="text-align:right; ">-0.99%</td><td style="text-align:right; ">0,78%</td><td style="text-align:right; ">-0.99%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >6</td><td style="text-align:right; ">-0.83%</td><td > </td><td > </td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >7</td><td style="text-align:right; ">-1.14%</td><td > </td><td > </td></tr><tr style="height:32px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >8</td><td style="text-align:right; ">-0.91%</td><td style="text-align:right; ">1,01%</td><td style="text-align:right; ">-2.88%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >9</td><td style="text-align:right; ">0.01%</td><td style="text-align:right; ">-2,27%</td><td style="text-align:right; ">0.01%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >10</td><td style="text-align:right; ">0.14%</td><td > </td><td > </td></tr><tr style="height:32px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >11</td><td style="text-align:right; ">0.31%</td><td style="text-align:right; ">0,27%</td><td style="text-align:right; ">0.45%</td></tr><tr style="height:19px ;" ><td style="font-size:8pt; background-color:#cacaca; text-align:center; " >12</td><td style="text-align:right; ">0.06%</td><td style="text-align:right; ">2,58%</td><td style="text-align:right; ">0.06%</td></tr></table><br /><table style="font-family:Arial; font-size:10pt; border-style: groove ;border-color:#00ff00;background-color:#fffcf9; color:#000000; "><tr><td ><b></b></td></tr><tr><td ><table border = "1" cellspacing="0" cellpadding="2" style="font-family:Arial; font-size:9pt;"><tr style="background-color:#cacaca; font-size:10pt;"><td >Cell</td><td >Formula</td></tr><tr><td >C2</td><td >{=IF(B2="","",IF(D1<>"",A2,SUM(INDIRECT("A"& MAX(IF($B1:B$2<>"",ROW($B1:B$2)))+1 ):A2)))}</td></tr></table></td></tr></table>

Array formulas
Entered with Ctrl+Shift+Enter. If entered correctly, Excel will surround with curly braces {}.
Note: Do not try and enter the {} manually yourself

Thanks guys. Both formular works fine. Have a great weekend!

Or, the simple way

=IF(B3="","",SUM(A$2:A3)-SUM(E$1:E2))
