How to unselect radio buttons

[Tracy Zhu]

Hi!

Am new to this community and confiforms!

Ive created a form with a list of questions/options and used radio buttons for number selection: 1, 2 and 3

How do I unselect a number from question/option 1, so no numbers are selected?

So for example: for QN/Option 1, if I picked a radio button with the number 1 next to it but decide i want want to untick it later on.. How would I do that?

Is there a rule that I need to use? if so, what is the rule pls?

Or is there a better option for my form?

thank you
Tracy~
