My apologies if this question has been asked before.

I have a list of vendors and amounts paid for each of their invoices.
I want to automatically add the payments to each vendor.

TOTAL
VENDOR INVOICE PAID PAID
A 100 4526
A 250 4625
A 578 4626 928
B 10 SC17
B 186 SC350 196
C 541 Inv 56
C 325 Inv 78
C 18 Inv 102 884

What formula would do that without having to go and write a standard
Sum formula after every change of vendor?

Many thanks

in D3:
=IF(A4=A3,"",SUMPRODUCT(--($A$3:$A$1000=A3),--($B$3:$B$1000)))
and fill down

Thank you very much for your effort, Klaus.

I copied your formula all the way down in col D and it was effective in detecting the change in the name of the vendor, however it gave the "#VALUE!" every time as the answer.

I also noticed that the sumproduct part of the formula will never capture the values in col C, 100+250+578=928 for vendor A of the sample) which is what I need. It may be because the formatting of my message was altered.

Thanks again Claus.

I did look at the suggested URL and it shows the formatted sample, as I sent it.

Would it be possible for you to please write the formulas in col D, so that the 928, 196 and 884 are calculated automatically by adding the values in col B for every vendor.

Thank you very much for your interest in helping.

it's not your sample - there are formulas in col D. You have to download
the sample to see it.

Sorry Claus,

I did it on the sample and it did work. I should have done this before I sent you my previous message.

Now I am going to translate it to the worksheet that I need.

Thanks a lot once more.

if you download the sample, the formula will translate automatically
