title: Error: Invalid left-hand side in assignment
body: <p>Ok, so I notice there are many people on stackoverflow getting this error, but most of them involve a bunch of jQuery stuff I haven't learned yet.  Anyway, I don't know what I could possibly be doing wrong here, but here's the code:
  var playerAnswer;</p>
  
  <pre><code>var computer;
  function getCompAnswer(){
  var x = Math.random();
  if(x &gt;= 0 &amp;&amp; x =&lt; 0.333333333){computer = "Rock";}
  if(x &gt; 0.333333333 &amp;&amp; x =&lt; 0.666666666){computer = "Paper";}
  if(x &gt; 0.666666666 &amp;&amp; x =&lt; 1){computer = "Scissors";}
  }
  
  &lt;!doctype html&gt;
  &lt;html&gt;
  &lt;head&gt;
    &lt;meta charset="UTF-8"&gt;
    &lt;meta name="viewport" content="width=device-width" /&gt;
    &lt;title&gt;Rock. Paper, Scissors&lt;/title&gt;
    &lt;link rel="stylesheet" href="style.css" /&gt;
  &lt;/head&gt;
  &lt;body&gt;&lt;form id="form-id"&gt;
    &lt;div id="test"&gt;&lt;/div&gt;
    &lt;script src="script.js"&gt;&lt;/script&gt;
  &lt;/head&gt;&lt;div class="formstyle"&gt;
  Choose one: &lt;br&gt;
  &lt;input type="radio" id="rock" name="game" onClick="retrievePlayerData();"&gt;
  Rock
  &lt;input type="radio" id="paper" name="game" onClick="retrievePlayerData();"&gt;
  Paper
  &lt;input type="radio" id="scissors" name="game" onClick="retrievePlayerData();"&gt;
  Scissors
  &lt;/div&gt;
  &lt;/form&gt;
  &lt;div id="play"&gt;&lt;/div&gt;
  &lt;div class="scoreboard"&gt;
  &lt;table&gt;
  &lt;tr&gt;
  &lt;th&gt; You
  &lt;/th&gt;
  &lt;th&gt; The Computer
  &lt;/th&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
  &lt;td id="playScore"&gt;
  &lt;/td&gt;
  &lt;td id="compScore"&gt;
  &lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/div&gt;
  &lt;div id="gamemsg"&gt;&lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
