Where can I program functions for Radio buttons?  Their names aren't appearing in the Programing window.

I am looking to have each button alter the static information, which should be as easy as some IF THEN statements, but I can't seem to find the field names.

Excellent, so now I can get into the programming statements for my radios - here is the next part of that question.

What defines that field.  Meaning I have
RADIO BOX (named radio_box)
OPTION 1 (named opt_1)
OPTION 2 (named opt_3)
OPTION 3 (named opt_3)

When I want to address each individual option using an if then statement - do I use:
IF radio_box = opt_1  (meaning opt_1 has been selected) OR!
IF opt_1 = "Y"

I apologize if these seem very rudimentary questions, but I can't seem to find a damnable thing about how option buttons work in any of the manuals and I'm not very good at programming *laugh*

Thanks.
