I’m not up to whatever you’re doing here but from reading the error, it seems the select element should be within a label element, yours isn’t here.
I don’t know what they mean, I’ve tried putting the select elements inside the label bt it keeps giving the same errror
<fieldset>
<label>Upload a profile picture: <input type="file" /></label>
<label>Input your age (years): <input type="number" min="13" max="120" />
</label>
<label>How did you hear about us?
<select>
<option></option>
<option></option>
<option></option>
<option></option>
<option></option>
</select>
</label>
</fieldset>
Explanation:
You have the select element:
<select> bla bla bal other stuff </select>
You should nest it inside a label element:
<label><select>bla bla bla other stuff</select></label>
And then you should also add text:
<label>Text goes here<select>bla bla bla other stuff</select></label>
