Я крайне сбит с толку тем, что я делаю неправильно. При нажатии кнопки отправки не похоже, что она запускает какую-либо из моих функций. Консоль в Google Chrome не выдает мне никаких ошибок, и из того, что я просматриваю, не похоже, что я вижу какие-либо синтаксические ошибки. Пожалуйста, сообщите.

 function submitForm(e) // grab the click event
{
    e.preventDefault();  // prevent default event
