Try this in C1:

=SUMIF(B1:B3,12,A1:A3)

You can adjust the cell references for longer ranges, eg:

=SUMIF(B1:B15,12,A1:A15)

which you would not be able to do in your IF statements.

Hope this helps.

Hi All,
I have to check if there is data in B1:B3 (for example the entry '12') if
so, I need to add/sum the number that is written in the parallel cell in
A1:A3.
For example if in B1 = o,B2=12,B3=12 and in A1=1,A2=2,A3=3. then the total
(represent in cell C1) will be 5. I accomplished that by using IF sentence
for each entry. Is there a more smart way to do this?
Thanks a lot in advance
