I'm in a class until Thursday and may not have time to look at it.

Where are you creating your JTable and your DefaultTableModel?

Are you supposed to call setValueAt() yourself? In my mind, it gets called by the Java system when the user edits a cell. Maybe it should work the other way around too. If you haven't done so already, you may want to look at a tutorial and/or code example that does something similar (and point the rest of us to it, and we may help spot where you're breaking the assumptions of the example, maybe?).
