How can I target three IDs with the same function?
<p>I'm trying to apply the same function to three different IDs. I've created a fiddle to illustrate this: <a href="https://jsfiddle.net/jnoweb/xrpsshcp/" rel="nofollow noreferrer">https://jsfiddle.net/jnoweb/xrpsshcp/</a></p>

<pre><code>var game = {score:0},
scoreDisplay = document.getElementById("score1");

function add20() {
  TweenLite.to(game, 1, {
      score:"+=20", 
      roundProps:"score", 
      onUpdate:updateHandler, 
      ease:Linear.easeNone
  });
}

function updateHandler() {
  scoreDisplay.innerHTML = game.score;
}

add20(); 
</code></pre>

<p>So I'm trying to animate the black numbers in the same way as the red number. Any ideas?</p>

<p>Thanks!</p>
