I would like to have 12 option buttons grouped together in each row.
The option buttons for each row should be independent of the ones in
the other row.

I added option buttons from the forms toolbar for the first row and
drew a group box around them. I did the same for the second row. After
selecting a box on the first row, I then select a box on the second
row. Selecting a box on the second row deselects the box on the first
row. Both rows are being treated as one group. I need them to be
independent. The user should be able to select one option for each row.

I've tried setting the cell link to the first cell for each row under
Format Control. But setting the cell link to the first cell in row 2
also changes the cell link to the same value in row 1. In other words,
I'm not able to have A1 as the cell link for row 1 and A2 as the cell
link for row 2 at the same time. It's always A1 for both rows or A2 for
both rows.

What am I doing wrong? Should I be using the forms toolbar or the
control toolbox? It seems that it should be very straightforward.
