title: How to fix: PHP Notice: Undefined Index
body: <p>In the form I'm creating I have a multi-select that doesn't want to update. The debug log point me to this line of code but I'm just a noob WordPress-user so I have no idea what I'm supposed to do with it.</p>
  
  <p>I've tried removing the form and using a new one and just using the plugin along with the standard Twenty Fifteen theme though nothing seems to work.</p>
  
  <pre><code>$stripslashes = $args['submitted'][ $key ];
  </code></pre>
