If your values in column A are numbers, try
=SUMPRODUCT((ROUND(A5:A100-INT(A5:A100),1)=0.1)*B5:B100)

If they are text strings, try
=SUMPRODUCT((RIGHT(A5:A100,1)="1")*B5:B100)

Hi.

My value in column a a

1.2
7.1
4.2
4.1
.....

if the the value is 1 I want to SUM.

such as 7.1 and 4.1

if you make a right 1 to this you will get the result = 1

So I want to sum if right is 1, witch will sum 4.1 and 7.1


Regards,
Marco

Hi. I need to make a sum if from A5 to B100 if right A5:A100 =1

So what I mean is only sum if right A = 1

when I say A I mean:


A1
A2
A3
A....


regards,
Marco

This formula will sum values in B5:B100 where the corresponding value in
A5:A100 equals 1:
=SUMIF(A5:A100,1,B5:B100)

I don't understand what you mean by "right A", though. Post back
explaining
this if you need more help.
