hi, im working on a GUI for a class project. the idea is for a sports team/player stat tracker.

to change player stats we have a combo box to select a team which effects a "player" combo box to show the proper players for the selected team on the same menu. we are supposed to research how to do this and i just felt this is the best place for that.. any help?
(we are using Netbeans GUI builder for the project)
