Your code seems pefect…
1.you should use another browser

Hi @suyogkandel ,

Actually, your radio button needs to be within the form element( between the opening form tag and closing tag ), just above the text input.

The code was fine. Browser was the issue.
and I don’t know what the f are you talking!

Are you sure ? I don’t think the challenge would pass with the radio input out of the form.
