Need to add every third value in a row of data
Hi,
I need to add every third value in a row of data and I do not know how. Thank you, Benedict |
Need to add every third value in a row of data
Try this:
=SUMPRODUCT(--(MOD(ROW(A1:A100),3)=0),A1:A100) Assumes you are trying to add from column A - adjust to suit. It will add rows 3, 6, 9, 12 etc. Hope this helps. Pete On Sep 19, 3:02*pm, baurian wrote: Hi, I need to add every third value in a row of data and I do not know how. Thank you, Benedict |

Just noticed you said the data is in a row. Change the formula to
this: =SUMPRODUCT(--(MOD(COLUMN(A2:AA2),3)=0),A2:AA2) This looks at row 2 and adds every third column from C onwards. Hope this helps.

Thank you, Pete. It works with numbers; it does not seem to work with (date
time) in the cell. Benedict "Pete_UK" wrote: Just noticed you said the data is in a row.

If they are Excel data/times they are numbers, maybe you only need to format
it the right way like [h]:mm etc or maybe they are text but look like numerical dates times? -- Regards, Peo Sjoblom "baurian" wrote in message ... Thank you, Pete.
