Change "single choice" field based on condition

Hi!

How to change single choice field state based on condition? For example, take a look at screenshot: when user selects something special in dropdown menu, the single choice below must change it's state.

When using update/calculate form field conditions to update radio fields, use the text of the option for the output field as the entry in the equation:

The form will check the output field for the option that matches the text in the equation.

Here is a quick example form to show how it would work:
