Я работаю над этой формой PHP и продолжаю сталкиваться с этой проблемой.

Когда я пытаюсь отправить электронное письмо, оно говорит, что у меня есть неопределенная переменная в строке 81:
$stateSelect = isset($_POST["stateSelect"]) ? $_POST["stateSelect"] : $stateSelect ;
Когда я удаляю последние $stateSelect и добавляю "", это устраняет ошибку, но затем, когда я отправляю форму, это поле отображается пустым.
$country и $stateSelect - выпадающие списки. Все, что я выберу в $country, влияет на выпадающий список $stateSelect.
