java.lang.IllegalArgumentException

It appears that I am passing an illegal or inappropriate argument, be darned if I can figure it out.

Anyone have any ideas?

The error occurs at getValueAt(), first listing.

The data and getter methods are in the second listing below.

Thank you.

JS.

privateboolean DEBUG =false;

private StringBuffer sbSix=new StringBuffer("initsbSix");

table.setPreferredScrollableViewportSize(new Dimension(500, 70));

//Create the scroll pane and add the table to it.

//Add the scroll pane to this panel.
