Nevermind, Nick. I found out why it wasn’t working. Functions.php and Scripts.php were calling fitVids.js, when indeed it is called FitVids.js (with a capital F), so that was the issue. Got it all sorted out. Thanks again.
To be quite honest, I know almost next to nothing when it comes to JavaScript, so if you could point me in the right direction that would be very helpful. Thank you.
