title: How do I make 1 "oninput" field yield multiple "output" fields?
body: <p>What I mean is, I want someone to be able to enter a number into an input box, and it have it yield a range. So if they enter the number <code>2</code>, it shows an output of <code>2*300-2*400 (600-800)</code>.</p>
  
  <p>I have been using</p>
  
  <pre><code> &lt;form oninput="x.value=parseInt(a.value)*parseInt(300)"&gt;
  
   &lt;input type="text" name="a" value=""&gt;
  
   &lt;output name="x" for="a b"&gt;&lt;/output&gt;
  </code></pre>
  
  <p></p>
  
  <p>However that only yields the <code>variable*300</code>. How do I get a second output box directly after the first with the <code>variable*400</code>?</p>
