breeze76 on "[Plugin: Contact Form 7] How to have a radio button selected?"

I kind of understand what you are saying, but I am still lost...

Here is my code:

<p>Do you need us to provide a location? <br />
    [radio radio-no1 label_first "NO"] [radio radio-yes1 label_first "YES"]</p>

I want to have no selected but if they select "YES" the "NO" is unselected.
