Radio_button with arrays

Hello-

I would like to display a list of (say 5) groups of radio buttons. Each
group may have a variable number of choices. I’m wondering how to pass
the initial values (controller->view) and how to get them back out
properly.

Essentially, the result should look something like:
radio[0] = 3 (choices were 3, 15, 32)
radio[1] = 14 (choices were 1, 14)
radio[2] = 44 (choices were 42, 43, 44)
radio[3] = 97 (choices were 0, 1, 97, 43, 32, 35)

and so on.

Any suggestions would be very helpful.

Jake
