--description--

Notice that both radio buttons can be selected at the same time. To make it so selecting one radio button automatically deselects the other, both buttons must have a name attribute with the same value.

Here is an example of two radio buttons with the same name attribute:

html
<input type="radio" name="meal"> Breakfast
<input type="radio" name="meal"> Lunch

Add the name attribute with the value indoor-outdoor to both radio buttons.

--hints--

Both radio buttons should still be located between opening and closing label element tags.

js
const labelChildNodes = [...document.querySelectorAll('form > label')].map(
  (node) => node.childNodes
);
assert(
  labelChildNodes.filter((childNode) => childNode[0].nodeName === 'INPUT')
    .length === 2
);

Both radio buttons should have a name attribute. Check that there is a space after the opening tag's name and/or there are spaces before all attribute names.

js
const radioButtons = [...document.querySelectorAll('input[type="radio"]')];
assert(radioButtons.every((btn) => btn.hasAttribute('name')));

Both radio buttons should have a type attribute. Check that there is a space after the opening tag's name and/or there are spaces before all attribute names.

js
const radioButtons = [...document.querySelectorAll('input')];
assert(radioButtons.every((btn) => btn.hasAttribute('type')));

Both radio buttons should have a name attribute with the value indoor-outdoor. You have either omitted the value or have a typo. Remember that attribute values should be surrounded with quotation marks.

js
const radioButtons = [...document.querySelectorAll('input[type="radio"]')];
assert(
  radioButtons.every((btn) =>
    btn.getAttribute('name').match(/^indoor-outdoor$/)
  )
);
