I think I did, but I omitted an = in the formula

=SUM (IF((A1:A100=1)*(D1:D100<""),C1:C100))

array as before.

But I get 300 not 200, I cannot see your logic for 200.

you didnt get what i meant
i only want to sum the numbers in third column if they only belonged to
one company(suppose company number 1 (microsoft)) and also if the
forth column have a value in it
so in that example
the summation of microsoft is 100+100=200
