vb .net 2k3 app using microsoft access 2k as db:

I want to be able to go through my data and find a new instance of one value
in column1. When I get a new instance I want to be able to look at the
values in column2 (only 5 values possible) and count the occurence of the
values. After that is done I want to go back to column1 looking for new
values. any ideas on how to do that?
