Urgent : I need help for fianlyse my custom component

[titoff000222]

Description problem
Hello, I created a custom component: I can display and use it. However, I can't get the value of "input[type="radio"][name="garantie"]:checked" and I can't make it required either. If someone could help me and tell me what's missing or what's wrong, you'll find my code below. And thank you in advance.
