Different Radio Button Fields: Select Only One

Hello unbounce community,

I have a form with two separate radio button fields. I need a rule that if you click in one radio button field, you can’t click in the second radio button field - and the other way round.

in addition, if the customer clicked on a radio button field, he should be able to remove his choice by clicking on it again.

how can i implement this in unbounce with javascript?
thanks for your help.
