The data is going to be large, that's why I will collect it on a spreadsheet.
Obviously I will have two columns, one with the category info and the other with
the products. I was thinking to make it based on a filter, but don't know how. I
know how two make it in MS Access, by means of a query, but not in Excel. If you
suggest me how to solve this "tinny" problem I will be very happy with my boss.
I promised him this problem can be solved, taking into consideration the help  I
can get from you. I told the boss how you helped with the combo  box problem, he
was very exited.
