Sum of multiple cells substring

users
#1

Hi, I have a table with cells that may contain OTnum, so it might contain OT0.5, OT1, OT2, OT2.5 et cetera.

I would want to sum the number substring of all the cells in a row, so for example if I have this row:

Alan OT0,5 F OT1 F V OT2 F F V OT3

I would have another column with the total sum of OT:

Alan OT0,5 F OT1 F V OT2 F F V OT3 6,5 (OT3+OT2+OT1+OT0.5)

I have tried with the formula =SUMPRODUCT(MID($B5:$AF5,FIND("OT",$B5:$AF5,3))), but I am not actually sure what I am doing.

Thanks.

Suppose those eleven items are cells A1 to K1. In the result cell, enter
=SUM(IF(LEFT(B1:K1,2)="OT",VALUE(MID(B1:K1,3,99)),0))
But don't press Enter or click the green tick mark; instead press Ctrl+Shift+Enter to render it an array formula. You will see that the entire formula displayed in the Input Line has been surrounded by braces - { } - but note that you cannot achieve the same result by typing these yourself.

You will presumably need to copy this formula down a column. If so, you appear to be able to achieve the correct result by copying the formula from the first cell and pasting it into others (even wholesale) or by using Edit | Fill, but not by dragging the fill handle.

I trust this helps.

Hi again,
I modified the formula to suit my spreadsheet to {=SUM(IF(LEFT(B46:AE46,2)="OT",VALUE(MID(B46:AE46,3,99)),0))}. It works beautifully but, in some instances it will render an Err:502.
One of said instances is this:
OT8 HF8 OT8 OT2 OT1 OT0,5 OT8 OT8 OT8 OT5 OT6 OT5 OT6 OT5 OT5 OT8 OT5 OT6 OT3 OT8 OT8 OT4 OT8 OT8 OT5 OT1 OT5 OT4 OT8 OT8

Is the HF8 the one to blame?

Thanks again.

Hello again!

I realized the error was that the decimal point is a , (we are using Spanish localization), so changing the , for a . decimal point did the trick.

Once again, thank you a lot.
