Button press to reset field value to ""

[astello]

I am having trouble setting a rule for a button that, when pressed,
should reset a radio button's value to "", or basically unselect a
radio button. The part I'm having trouble with is the button press
condition. How do I write a condition for "when 'button' is pressed"
- is the value for a pressed button "true"? "yes"? etc.?

I'm not great with code, so if you have guidance on setting the rule
in the button properties, please let me know. Thanks in advance!

What you would do is assign the radio button a default value... it can
be either "Yes" or "True". Then what you would do is write a rule for
the button action saying: Set a fields value: "Radio Button Field
Name" to "Value"
