Desafío: Aprende formularios HTML construyendo un formulario de registro - Paso 38

Enlaza al desafío:

Casi lo tienes

Este es tú código:

      <fieldset>
        <label for="profile-picture">Upload a profile picture: <input id ="profile-picture" type="file" /></label>
        <label for="age">Input your age (years): <input id ="age" type="number" min="13" max="120" /></label>
        <label for="referrer">How did you hear about us?
          <select>
            <option value="">(select one)</option>
            <option value="1">freeCodeCamp News</option>
            <option value="2">freeCodeCamp YouTube Channel</option>
            <option value="3">freeCodeCamp Forum</option>
            <option value="4">Other</option>
          </select>
        </label id="referrer">
        <label for="bio">Provide a bio:
          <textarea id="bio"></textarea>
        </label>
      </fieldset>

fíjate que la mayoría cumple:

profile-picture:
  <label for="profile-picture">Upload a profile picture: <input id ="profile-picture" type="file" /></label>

age:
  <label for="age">Input your age (years): <input id ="age" type="number" min="13" max="120" /></label>

bio:
   <label for="bio">Provide a bio:
   <textarea id="bio"></textarea>

y mira el referrer como lo hiciste:

<label for="referrer">How did you hear about us?

          <select>
            <option value="">(select one)</option>
            <option value="1">freeCodeCamp News</option>
            <option value="2">freeCodeCamp YouTube Channel</option>
            <option value="3">freeCodeCamp Forum</option>
            <option value="4">Other</option>
          </select>
</label id="referrer">

Porque añades el select dentro del label?

hazlo igual como lo hacias antes:

  <label for="referrer">How did you hear about us?</label>
  <select id="referrer"> //el id va aquí
     <option value="">(select one)</option>
     <option value="1">freeCodeCamp News</option>
     <option value="2">freeCodeCamp YouTube Channel</option>
     <option value="3">freeCodeCamp Forum</option>
     <option value="4">Other</option>
  </select>

Saludos

<label for="referrer">How did you hear about us?
          <select>
            <option value="">(select one)</option>
            <option value="1">freeCodeCamp News</option>
            <option value="2">freeCodeCamp YouTube Channel</option>
            <option value="3">freeCodeCamp Forum</option>
            <option value="4">Other</option>
          </select>
        </label id="referrer">

Revisa esta parte de tu código como agregaste el id.

Los otros están correctos.
