All right, I've attached my form here. You can ignore the top section and Storage/Thermal Shock rows, I'm currently working with the "Operating" row in the Temperature section.
Expected functionality:
When a radio button is selected on the "ViewTestSelection" view, the boxes on "ViewTestOrder" will update accordingly. field67 should update with the appropriate column title (e.g. "Level 1", "Level 4", "User Defined", etc). field68 should update with the appropriate temperature range (40C to 125C, 25C to 80C, etc).
I tried to match the syntax of your example as well as possible, by setting the default values of field67 and field68. However, the fields remain blank, even after selecting the radio button options.
Please let me know what you find out.
