Yes or no field = entry in another field

[Maxwell Morlay]

I have a field with "yes" and "no" radio buttons. I want a second field to automatically enter "none" if the "no" is selected in the first field. How do I do it, please?

Thanks for your help.

SecondField (calculation, text) = If(FirstField = "no", "none", "")

This assumes that first field is a text field.
