Question about one of the bonus goals for the pet website

I was trying to figure out how to disable the button when the checkbox is not checked, but now, when it gets checked, it gets blocked and can't be unchecked. 

const $addPet = $("#add-pet");
const $terms = $("#terms");

$addPet.prop("disabled", true);

$terms.on("change", function() {
  if ($terms.prop("checked", true)) { 
    $addPet.prop("disabled", false);
  } else {
    $addPet.prop("disabled", true);
  }

});

Hi, in your if statement, I think you want test the property "checked" of $terms, right ? So you need to use .prop() with only 1 argument in order to make it return a boolean : true or false.

if ($terms.prop("checked")) {
// ...
}
Did it help ?
