replace Microsoft with a cell where you put the company name or with one of
your numbers (1 for Microsoft?)

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
