I had this working before and for some reason the script no longer works. I've been spending ages trying to solve it but can't seem to find the reason. I just want my video to pause upon clicking.

var video = document.getElementById("myVideo");

var btn = document.getElementById("myBtn");

function myFunction() {
  if (video.paused) {
    video.play();
    btn.innerHTML = "Pause";
  } else {
    video.pause();
    btn.innerHTML = "Play";
  }
}

And here is the HTML code:

    <video autoplay muted loop id="myVideo">
    <source src="video.mp4" type="video/mp4">
    </video>

  <button id="myBtn" onclick="myFunction()">Pause</button>
