Why after I have add labels to each of them and the compiler says that it looks like task 3 is no longer working?

Hi Tao

You get that kind of bummer because you write the wrong code on the task 4 so it makes the challenge confused that your task 3 is not passed.

If you've passed task 3, your code should be like this:

<label>Shirt Size</label>
<input type="radio" id="small" value="small" name="shirt_size">
<input type="radio" id="medium" value="medium" name="shirt_size">
<input type="radio" id="large" value="large" name="shirt_size">

So at task 4, it's asked you to create and associate a label with each of the 3 shirt size radio buttons. It should be like this <label for="###">###</label> and don't forget to it before <input>.

Hope this helps.

Hiya!

That error is because a change was made to your task 3 item when you did task 4.

Unless the challenge asks you to add a new statement to a previous task's block of code, treat tasks independent of one another.

Hope that helps!

No problem Tao! Good luck :)
