Problem adding up numerical results from index calculations

Copper Contributor

I wish to add up the numerical results of a series of index calculations. The index calculation result is showing on the sheet, but when I try and add up the column by typing in sum(b5:b42) it comes up blank. What am I doing wrong?

Sum will work when I have a column of figures produced using countif, but not the figures produced by index.

Looks like your data is getting converted to text and therefore does not result into a numerical summation. Try using Value function around Index to convert the data into numerical and then use sum as you are doing.

 

=VALUE(INDEX(your index array and match))
Demo formula in German:
INDEX('tabelle1'!$B$77:$M$77;;C1)+INDEX('tabelle1'!$B$70:$M$70;;C1)

Demo Formula in englisch:
INDEX('tabelle1'!$B$77:$M$77,,C1)+INDEX('tabelle1'!$B$70:$M$70,,C1)

Think this will solve your problem.

I would be happy to know if I could help.

I wish you a long life with health, joy and love.

You may use double dash to convert texts to numbers

=SUM(--B5:B42)

but better to adjust initial formula to return numbers instead of texts.
