The requirement: “13. Inside the form element, I can select a field from one or more groups of radio buttons. Each group should be grouped using the name attribute.”
Passed all the other requirements except the radio button one. Any help would be very much appreciated 
EDIT: RESOLVED. It works randomly after a few refresh…
