JCheckboxes order

[Armaron]

Ok, this problem is giving me a mind.... Let me explain.

I'm making a program where you can click on checkboxes and radiobuttons and it would have to export the choices to an excel file. Image of the application.

But when I process the data, he first takes the textbox. Then goes to the last checkbox of the first column, then goes through the list top to bottom of the first column. Then goes to the second column, first takes the value from the last checkbox and then the rest of the column. Then to the third column, takes the last checkbox's value and then the rest of the column.

Example (each number would be the id of a checkbox):
1 4
2 5
3 6

Order he gives me them: 3 1 2 6 4 5
Order I want them: 1 2 3 4 5 6

Does anybody know what attribute I can adjust to get them going from the first checkbox to the last? I'm using JCheckboxes. Each set of checkboxes is placed inside it's own JPanel.
