I have on eproblem. I have a table that contains two columns. One is type of
product(I have 6 different products)and another is quality characteristic for
those products. I need some function that can look at the first column and
returns vector with the values just for one type of product. If that is
possible I would then use that vector to put in countif function in order to
get percentages of different product ranges for that characteristic.
