title: comma separation for numbers in Framer
body: <p>I have a dynamic text layer with a number</p>
  
  <pre><code>dollarAmountValue = 9000
  dollarAmount = new Layer
  dollarAmount.html = "$" + dollarAmountValue
  </code></pre>
  
  <p>I also have a + and - button that increments dollarAmountValue by 100</p>
  
  <pre><code>dollarPlus.onClick -&gt;
      dollarAmountValue = dollarAmountValue + 100
  
  dollarMinus.onClick -&gt;
      dollarAmountValue = dollarAmountValue - 100
  </code></pre>
  
  <p>So the dollar amount displays as $9000, all good. What I'm trying to do is display it as $9,000 and have the comma separation for 1000's as the +/- increment buttons are pressed. Any help would be greatly appreciated. Thanks!</p>
