title: setInterval is not a function
body: <p><code>var intervalID = setInterval(funkey2, inter)();</code></p>
  
  <p>In the Chrome console, I get this error:</p>
  
  <p><a href="https://i.stack.imgur.com/QRiuj.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QRiuj.jpg" alt="enter image description here"></a></p>
  
  <p>but when I don't have line 24, the function never runs. The stop button doesn't work for some reason. I'm using <code>setInterval</code> for the first time so thanks for the help.</p>
